Single-Phase Power Circuit Protection By Phoenix Contact

Latest News

The BT-1S-230AC/O type 3 protector from Phoenix Contact offers surge voltage protection for loads in single-phase power circuits with 230 V AC nominal voltage. The main areas of application for these universal modules are installation sockets, dado trunking, under floor installations and connection spaces in end devices.

The protection circuit limits transient surge voltages between active wires and to the protective conductor. A temperature fuse monitors the surge protection circuit. When there is overloading due to surge currents, a red LED indicates that the protective function is impaired.

There are connection terminals with spring-cage direct plug technology for every two L, N and PE wires. This also enables installation as feed-through wiring.
