Phoenix Contact electronic and thermomagnetic circuit breakers

Phoenix Contact’s latest range of electronic and thermomagnetic circuit breakers protects devices from surges and short circuits, even when long cables are used.

The one-channel, pluggable circuit breakers enable modular designs for selective power distribution. Coding between the base element and the plug ensure error-free placing and a new connector catch mechanism holds circuit breakers securely in place.

Push-in connection terminals make it possible to connect wires without tools and a bridge system allows all circuit breakers to be readily combined, according to requirements.

The thermomagnetic circuit breakers are distinguished by their optimised SFB tripping characteristic. In combination with Selective Fuse Breaking (SFB), the technology in use in QUINT Power power supply units, the circuit breakers offer high cut-out protection in case of a fault.

The electronic circuit breakers work with active current limitation. This delays immediate cut-outs due to temporary power surges.
