WAGO’s ECBs have a lot to offer:
Product Overview
Discover Our ECBs
The new modules are just 6 mm (0.236 inch) wide, making them the slimmest ECBs currently available. They are approximately 66 % smaller than miniature circuit breakers, saving even more space, particularly when used in control cabinets. These ECBs enable high-capacity loads greater than 50,000 microfarads to be switched on – helping you reduce false tripping due to inrush currents.
Advantages:
WAGO’s space-saving ECBs provide reliable protection with a superior price/performance ratio. They offer both outstanding features and reliable protection against overload and short circuits. With a maximum width of 45 mm (1.772 inches), these ECBs feature high channel density to save space in the control cabinet.
Advantages:
Compactness without Compromises:
Width of just 6 mm (0.23 inch) maximizes panel space
Marking:
Device identification via WMB Markers or TOPJOB® S Marking Strips
Trip Characteristics:
Reliable, rapid and precise disconnection in case of overcurrent or short circuit
Models Differentiated Visually: Devices color coded according to rated current
Simple Wiring: Bridgeable signal output and total reset for up to 30 devices
Save Space in the Control Cabinet:
Up to eight channels in just a 42 mm (1.653 inch) wide module
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 detecting hazardous ground faults in control circuits and switching them 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.

Explanation:
ECBs ensure reliable protection, even at low overcurrents and with long cable lengths.
The ECB checks whether 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. Trip time depends on the magnitude of the overcurrent. The measurement of the output current, the processing and calculation of the tripping time and the actuation of the semiconductor switch are performed by a microprocessor that monitors one or more output channels. The corresponding tripping times can be found in the graph on the right.
The electronic circuit breaker can be reset via digital control signal. The 787-2861 ECB can also be switched on and off with this control signal. A digital output signal indicates the status of the channel or the sum of the channels for 787-166x ECBs. For some devices, this signal is potential-free (P).
The PLC transmits a coded pulse pattern to control input S1. The ECB synchronizes itself automatically. The current status of all output channels is transmitted back simultaneously via signal output S2. The edge change is interpreted as high or low. Both the status and voltage/current values of each channel can be transmitted individually.
Via an IO-Link interface implemented in COM3, for each channel, both its status and its voltage and current values can be transmitted individually. The nominal output current can also be configured via this interface if the device's rotary switch is set accordingly. The IO-Link cyclic communication is much faster than the Manchester protocol.
