Product Details

Series 5SM3, Type B SEQUENCE, 4-pole

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


Systems with consumers in which smooth residual DC currents may also occur
Use in three-phase systems
