Three four-channel Electronic Circuit Breakers have joined 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 10A at 24VDC max each), while offering independent programming of 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 electronic circuit breakers can shut down the tripped channel within 100ms.

Rather than halting the entire system, power is maintained to other loads (e.g, to a PLC on one path and HMI on another).

This prevents a system-wide shut down, as well as possible data loss.

Afterward, the tripped load may be remotely reset via a control input.

Through free 759-860 visualisation software (and available RS-232 cable) or on-unit LCD, the 787 Series electronic circuit breakers provide independent channel monitoring of voltage, current, fault diagnostics and energy consumption.

Additional Electronic Circuit Breaker features include four current channels w/delayed switching-in of channels (250ms/channel), rugged metal housing, LED status indication, signal outputs and CAGE CLAMP Spring Pressure Connection technology for vibration, and maintenance-free terminations.

The circuit breaker features an integrated short-circuit current limitation, which avoids overload of upstream power supply units, guaranteeing definite shutdown selectivity.

The 787-860 and 787-862 do not feature short-circuit current limitation but have adjustable trip times for quicker responses than those of melting fuses or traditional circuit breakers.

Both units also allow for current path monitoring (e.g, overload or short circuit), as well as power consumption.

Modules are optimised for advanced applications, or those distributed over great distances and can be used behind primary switch mode power supply units with overload or short circuit behaviour.

If output of the power supply unit is divided into several circuit paths, the electronic circuit breaker will protect the circuit paths separately, making it suitable for control panels or machines powered by a single, larger power supply.

Monitoring capabilities are also ideal for applications where events must be logged (such as those in food, medical or process industries), where loads are separated over long distances (process), or if remote access is required (such as those in water/wastewater treatment and petrochemical facilities).
