Why Secondary-Side Fuse Protection?

On the secondary side, switched-mode power supplies provide DC voltage to control circuit loads (e.g., controllers, operating panels, displays and auxiliary relays). These control circuits also call for wiring protection and if the load has no protective unit of its own, device protection as well. Furthermore, Machinery Directive EN 60204 requires the detection of hazardous ground faults in control circuits and switching off within five seconds.

The overcurrent protection in primary switched-mode power supplies reacts very quickly to overcurrents on the output side. Selective protection of individual current paths in the secondary circuit via fuses or conventional circuit breakers is often ineffective if the power supply cannot deliver a brief overcurrent.

What Types of Fuse Protection Are There?

Thermal

Possible applications:

Low-voltage, high-power and DP fuses
High overcurrents required for fast tripping

Explanation:

In the example: ten-fold overcurrent (related to fuse nominal current): tripping within the range 30 ms (best case) or 200 ms (worst case)
Only two-fold overcurrent: tripping within the range 2 s (best case) or >100 s (worst case)

Thermal and Magnetic

Possible applications:

Found in circuit breakers or motor protection switches
High overcurrents required for fast tripping

Explanation:

In the example: three- to five-fold overcurrent for B-characteristic and AC operation, additional safety factor 1.2 or 1.5
Thus, in the worst case scenario, a tripping current of 7.5 times the nominal current is necessary.

Electronic

Functions of a WAGO ECBs:

Ensure precision settings
Reaction within a short time – even at low overcurrents
Protection of long cable runs and small cross sections possible

Explanation:
WAGO ECBs ensure reliable protection, even at low overcurrents and with long cable lengths.

How Does an ECB Function?

The ECB verifies that the output current is greater than the nominal current. As soon as the output current exceeds the nominal current, the output is electronically switched off by a semiconductor switch. The trip time depends on the magnitude of the overcurrent. The measurement of the output current, processing and calculation of the tripping time, as well as actuation of the semiconductor switch are performed by a microprocessor that monitors one or more output channels. The corresponding tripping times can be taken from the graph on the right.

ECB Advantages:

Switch off secondary-side overcurrents and short circuits – even with long cable runs and small conductor cross-sections – precisely, quickly and repeatedly
Selectivity, especially with ECBs having active current limitation
Remote operation via digital input and output
Readout functions (communication) through serial data transfer via digital input and output
Advantageous installation size and width, for example, eight output channels in just 42 mm (1.653 inch) that saves more than 70% of installation space compared to miniature circuit breakers
Nominal current assignable for each channel
Satisfy EN 60204-1 requirements for dependably switching off ground faults after five seconds

Communication

Communication 1.0

Digital signaling (S/P)

Remote digital input resets all tripped channels
Digital output transmits a simple group message indicating whether one of the channels was tripped by an overcurrent
