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.
