All-current-sensitive FI circuit breaker for detection of residual AC currents, pulsating and smooth residual DC currents Increased operating reliability in networks with capacitive impedances based on adapted actuation characteristic Switch handle and test button may be locked via handle lock Time-delayed disconnect function in the event of transient stray currents High current capacity < 3 kA
Applications:
Systems with consumers in which smooth residual DC currents may also occur Use in three-phase systems
