Wago 4-Channel Electronic Circuit Breakers
Wago Corp. 787 Series DIN-rail mount, 4-channel Electronic Circuit Breakers (ECBs) separately protect up to four current paths (up to 10 A at 24 V dc max each) for power supplies without a “top boost” feature. Wago has deemed this line of ECBs as ideal for multiple loads distributed from a single power supply. Several models independently program four load-appropriate current ratings (in 1 A increments), as well as trip times. During a fault or short circuit, the ECBs can shut down the tripped channel quicker than fuses or conventional mini-circuit breakers. Power is maintained to other loads (such as a PLC on one path and HMI on another), preventing a system-wide shut down or possible data loss. Active current limitation on the 787-861 model protects an upstream power supply, guaranteeing selective load disconnection. Tripped loads may be reset with on-unit keypad or remotely via control input. ECBs streamline control panels by eliminating redundant power-monitoring components. Select ECBs provide superior energy monitoring and fault diagnostics via on-unit LEDs, LCD/keypad, signal outputs, and RS-232 interface. Free Wago software provides remote monitoring.
