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:
Industry's Most Compact:
Width of just 6 mm (0.23 inch) maximizes panel space

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.” For each channel, both status and voltage/current values 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.
