Differential circuit breaker RECmaxLPD series

earth-leakagethree-phasesingle-phase

Self-resetting cut off device with circuit breaker and ultra-immunized earth leakage protection. Programmable unit with display, which measures leakage currents (earth leakage protection), and orders the disconnection or reclosing of the circuit breaker (circuit breaker protection) through a motor that controls it mechanically. The leakage current measurement, IΔ, needs an external earth leakage transformer, which is supplied separately. The assembly is regularly used in electrical, single-phase and three-phase installations that require high continuity of the electric supply. It has inputs/outputs which provide information and control on the state of the electrical installation where it is working. LED display and backlit (LCD) display: Earth leakage protection/reclosing parameters. Protection trip current. Number of reclosures Protection status messages, etc. Applications The RECmax LPd connected to the WGC toroidal transformers ensure earth leakage and circuit breaker protection with self-reclosing after an earth leakage, overload or shortcircuit trip. It is a good solution for those infrastructures that are hard to control and monitor because of their location in the following control boards: Telephony systems DTT systems Computer systems, UPS
