Electronic Circuit Breakers (ECBs)

A high switch-on capacity is combined with an electronic relay.
WAGO's space-saving ECBs come into play when the focus is on both safety and a superior price-performance ratio.

ECBs from the EPSITRON^® family have a lot to offer:

They offer reliable protection against overload and short circuit.
They also enable activation of high-capacity loads of 50,000 microfarad and higher – without having to increase the nominal current setting.
One, two-, four- and eight-channel models with 0.5 to 12 A current ratings offer you the flexibility you need for setting the nominal current to suit your individual applications.
With a maximum width of 45 mm (1.772 inches), these ECBs feature high channel density to save space in the control cabinet.
Some devices are also available with active current limitation, preventing the power supply unit from overloading during a short circuit.

Protect Small Currents Easily

New WAGO 0.5 A Electronic Circuit Breaker

With WAGO’s single-channel circuit breaker (787-2861/050-000), even small load currents of 0.5 A can now be easily protected in control circuits. Quick, reliable tripping after 4 ms is guaranteed with all seven available circuit breakers. In addition, the circuit breaker saves space in the control cabinet or system distribution box with its overall width of just 6 mm. Different control options for the integrated digital input allow channels to be set to a specific state, increasing usability. The digital output reports the current status. Since they have the same profile, direct commoning of the input and output voltages is possible across 857 and 2857 Series devices.

The Benefits for You:

Protection of load currents from 0.5 A to 8 A
Slim 6 mm (0.236 inch) housing saves space
Reliable tripping of the circuit breaker after just 4 ms

Single-Channel ECBs

With a width of only 6 mm (0.236 inch), these new circuit breakers are the narrowest ECBs currently on the market. They are approximately 66% smaller than miniature circuit breakers to save even more space, particularly when used in control cabinets. These ECBs enable high-capacity loads greater than 50,000 microfarads to be switched on, without requiring further action or changing the nominal current, helping reduce false tripping due to inrush currents.

Your benefits:

24 VDC / in six versions for rated currents of 1 to 8 A
With devices color coded according to nominal current
An extremely slimline version
Switch-on capacity: >50,000 µF
Wide operating temperature range: −25 … +70°C (−13 … +158°F)
Resetting, on/off switching directly on the module or remotely via digital input signal
Triggered signal output can also be combined as a group signal for up to 30 devices
