Compact Circuit Breakers with Ground Fault Protection

Leakage Current Protected Compact Circuit Breakers (Fire Protection Circuit Breakers) provide protection against leakage currents in addition to thermal-magnetic protection. Since they have an internal detection mechanism, they do not require a combination of an external toroidal current transformer, residual current detection relay, and trip coil. This minimizes the complexity of panel wiring, resulting in significant savings in both labor and installation space.
