WAGO Gelbox Protects Connectors from Moisture

Condensation, heavy precipitation, powerful water jets: When moisture meets electricity, a short circuit can happen quickly. Encapsulation is a proven solution. But now reliable moisture protection for splicing connectors can be achieved even more quickly and easily with the WAGO Gelbox. It is ready for immediate use in a wide range of low- and extra-low voltage applications.

The complete system consisting of Gelboxes and WAGO connectors has been VDE-tested and IPX8-certified.

What is the WAGO Gelbox?

The WAGO Gelbox is a compact box pre-filled with silicone-free gel. The Gelbox is available in nine sizes and provides IPX8 moisture protection for WAGO’s 2273 Series COMPACT PUSH WIRE® Connectors for Junction Boxes, as well as WAGO’s 221 Series COMPACT Splicing Connectors and Inline Splicing Connectors with levers. This protection type requires the connectors to be completely sealed off against water and able to withstand continuous immersion in water. Conventional potting compounds like polyurethane and silicone also meet IPX8 requirements,

but what’s special about the WAGO Gelbox is that it protects the electrical installations exactly where it matters – at the connection points – without permanently encapsulating the distribution boxes. Unlike silicone-based gel, the WAGO Gelbox’s silicone-free gel supports a virtually unlimited number of applications.

Where Can the Gelbox Be Used?

The WAGO Gelbox can be used in a wide range of low- and extra-low-voltage applications. However, its use differs somewhat among the specific voltage ranges. For example, in low-voltage applications (e.g., 230 V), the Gelboxes are used in junction boxes together with splicing connectors. This is the only way to ensure double cable insulation to protect against electric shock, since only the conductors are encapsulated in the WAGO Gelbox. In SELV (Safety Extra Low Voltage) applications, the WAGO connectors can be used with Gelboxes without an additional junction box.

How is the WAGO Gelbox used?

Installation is easy: Open the box, insert the connectors, close the box. In more detail: Open the WAGO Gelbox, place the wired splicing connectors in the box and close the box with slight pressure. The gel completely wraps itself around the installation.

Thanks to a compact design, WAGO Gelboxes can be easily accommodated in every junction box. Thanks to different housing styles, several connectors can be accommodated in one WAGO Gelbox to create additional space in the distribution box. If a circuit needs to be expanded, the boxes can be easily re-opened and quickly and reliably re-wired – a real advantage over standard electronics encapsulation. The wires that connected in the old installation can be reused for the new one. However, this requires new connectors and Gelboxes – this is the only way WAGO can guarantee the high degree of protection.

Why use the WAGO Gelbox?

The WAGO Gelbox offers completely new possibilities for protecting splicing connectors from moisture. This means that the boxes can be easily accommodated in any junction box – regardless of whether they are mounted on the wall or under the ceiling. First of all, the time required for mixing the components is eliminated. Secondly, additional time is saved because you do not have to wait until the mixed potting compound has finally hardened or dried. In addition, the gel is non-hazardous because its chemicals have already reacted, which makes the WAGO Gelbox ready for immediate use. The box is already prefilled with gel and seals the connection immediately, allowing electrical systems to be deployed right after installation without interruption – quickly, easily and reliably.

Cellpack-Quality Gel – Silicone- and Label-Free

WAGO relies on the proven quality of Cellpack-brand gel. This well-known potting compound manufacturer co-developed the Gelbox with WAGO. The Cellpack gel used offers three main advantages over conventional encapsulation. Chief among them: The gel is silicone-free. This allows the Gelbox to be used in any branch of industry – even those where varnishes, paints and other sensitive products are used, such as the automotive industry. Secondly, the silicone-free gel has already reacted, so it is fully label-free and can be stored indefinitely. This cannot be said of all components used to manufacture potting compounds. In addition, the silicone-free gel potting compound uniquely allows a user to re-access the connection – the keyword here: re-accessibility.

Is the WAGO Gelbox safe?

To ensure comprehensive safety, the developers of the WAGO Gelbox have focused on the overall system consisting of box, connectors and gel. The WAGO Gelbox meets the same tough test requirements as the WAGO connectors in compliance with EN 60998. The product’s high degree of safety is confirmed by a neutral party in the VDE test report.

Risk of short circuit: What causes moisture to form?

How do moisture and humidity form in a junction box? Condensation can arise from rapid temperature changes, for example. This is often the case during transitional periods, such as spring and autumn, when the warm air inside the housing meets the cold housing wall of the connector chamber and it cools down abruptly. The result: condensation on the housing’s inner wall. This physical effect is further magnified by power loss, which increases heat compared to the outside temperature.

These temperature differences also lead to pressure differences, which allow fresh air to flow into the connector over and over, introducing moisture. In total, a considerable amount of water can accumulate within the connector.

But heavy rainfall or a strong water jet too close to a distribution box can also cause moisture in junction boxes. “The moisture within the connector can then cause the current to take completely new paths, quickly leading to a short circuit.” However, this is often only noticed when protective devices are triggered, i.e., when the fuses blow.

FAQ

The WAGO Gelbox has only been tested and approved in combination with WAGO’s 2273 Series connectors and WAGO’s 221 Series COMPACT Splicing Connectors and Inline Splicing Connectors with levers for conductor cross-sections. It is available in nine sizes. Each box has a terminal diagram that specifies a fixed assignment depending on what connectors will be used.

Yes: The connectors are completely sealed against water and can be permanently immersed in water (however, with, for example, pressurized water, this is only permitted on the application side for complete cable sets).

The IPX8 protection type means that the connectors in the WAGO Gelbox are completely sealed against water and can also be permanently submerged in water. Basically, ingress protection (IP) codes are standardized according to DIN: the higher the number, the higher the degree of protection. With two-digit numbers such as IP68, the first number describes the protection against contact and dust (0 ... 6), the second the protection against water and humidity (0 ... 9).

Anywhere in the extra-low voltage range – so-called SELV (Safety Extra Low Voltage) applications – and low-voltage range (e.g., 230 V) where your electrical installation requires waterproof protection against moisture and humidity, without silicone. You can find possible applications here

The Gelbox is available in nine different sizes. Thanks to the different housing variants, multiple connectors can be housed in one WAGO Gelbox to free up additional space in the distribution box. Each box has a terminal diagram that specifies a fixed assignment depending on what connectors are used.

The wired splicing connectors are placed in the box. Then, the box is closed with slight pressure. The gel completely wraps itself around the installation. Please note the different ways it is used in the low voltage and extra-low voltage ranges, as well as the information on initial installation and rewiring.

The Gelbox can be stored indefinitely because the gel used has already reacted.

Yes, it’s label-free because the chemicals within the gel have already completely reacted. This means that the gel does not contain any hazardous substances in any concentrations that would require labeling based on the Ordinance on Hazardous Substances.

No: In order to ensure a high degree of protection, both the Gelbox and the connectors must be replaced when reinstalling or rewiring.

It depends on the voltage range: For SELV (Safety Extra Low Voltage) applications, an additional housing such as a junction box is not required. In contrast, the low-voltage range (230 V) does need one, because safety regulations require double insulation.

The WAGO Gelbox, combined with both the WAGO 221 and 2273 Series connectors, is VDE-tested to EN 60998 standards and is IPX8 certified.
