Hydraulic Magnetic Circuit Breaker


Carling Technologies' F-Series hydraulic magnetic high amperage circuit breakers are designed to handle high current applications in extremely hot and/or cold locations. The F-Series load sensing mechanism is insensitive to changes in ambient or enclosure temperature, providing a consistent trip point over temperatures ranging from -40°C to +85°C. Available with a choice of overload time delays, making them ideal for critical applications requiring inductive loads circuit protection.

Further, the F-Series breakers are available up to 700A and an optional 25 millivolt metering shunt construction provides a safe method for monitoring current flowing through the breaker by simply connecting a meter with light gauge wire to the appropriate terminals located on the shunt housing at the rear of the breaker. Applications can be customized by measuring and displaying percentage of current, watts or safe/danger zones.

1-3 poles; ratings from: 100 amps to 700 amps, up to 125 VDC/277 VAC; UL489 and 489A Listed, CUL Certified, TUV
