Four-Channel Circuit Breakers Sport Programmable Trip Characteristics

Three four-channel electronic circuit breakers have been added to WAGO’s 787 series power supply system. The DIN-rail mount 787-860, 787-861, and 787-862 electronic circuit breakers each protect up to four current paths (up to 10 A at 24 VDC max each). Designers can independently program appropriate channel- or circuit-specific ratings and trip times via free 759-860 configuration software. In the event of a fault or short circuit, the circuit breakers shut down the tripped channel within 100 ms. Rather than halting the entire system, power is maintained to other loads; for example, to a PLC on one path and HMI on another. This prevents a system-wide shut down and possible data loss. Afterward the tripped load may be remotely reset by means of a control input. The free 759-860 visualization software allows designers to program independent channel monitoring of voltage, current, fault diagnostics, and energy consumption. The electronic circuit breaker modules are ideal for control panels or machines powered by a single, larger power supply. WAGO CORP., Germantown, WI. (262) 255.6222.
