Carling Technologies is pleased to announce the new F-Series circuit breaker, designed to handle high current applications in extremely hot and/or cold locations. Given the same situation, a heavy duty thermal circuit breaker will either nuisance trip, or fail to trip fast enough to avoid damage to equipment.
The reason for the F-Series' superior level of performance is simple: It's a current sensing device employing a time proven hydraulic/magnetic design. The load sensing mechanism is insensitive to changes in ambient or enclosure temperature. Unlike a thermal circuit breaker, it doesn't rely on a bimetal's sensitivity to the electrical heating effect of current passing through the unit and the heat or cold of the environment surrounding it.
These high amperage hydraulic/magnetic circuit breakers provide a consistent trip point over temperatures ranging from -40°C to +85°C.
In addition, The F-Series comes with a choice of overload time delays, making them ideal for critical applications having inductive loads.
The initial product release covers maximum application ratings to 700 Amps with 125 VDC.
50,000 Amp interrupting capacity @ 125VDC.
Ratings above 250 Amps require a parallel pole configuration.
- CE marked (EN 60947-2)
- AC ratings approval are pending
- Additional constructions including optional low-voltage shunt for current metering will be available soon
