Hitachi Industrial Equipment Systems ZCT Built-in Wiring Circuit Breaker (Wiring Circuit Breaker)
Hitachi Industrial Equipment Systems
A wiring circuit breaker that achieves both early detection of insulation degradation and miniaturization of the panel with built-in ZCT.
By combining with a low-voltage insulation monitoring unit, early detection of insulation deterioration in equipment and preventive maintenance are possible. Additionally, the installation of a built-in ZCT breaker eliminates the need for a separate ZCT (enabling panel miniaturization and reducing wiring labor). - Panel miniaturization and reduced wiring labor are achievable (no need for ZCT penetration work on wires). - There is no need to place the ZCT separately (this is effective when existing wiring is complicated and installation is difficult). - It is helpful for the renewal of breakers (functional enhancement).
