Product details

The Siemens SENTRON 5SM3312-6BA is a 2-pole residual current circuit breaker (RCCB) rated 25 A at 230 V AC, with a 30 mA trip sensitivity and type A residual current detection — meaning it catches sinusoidal AC faults plus pulsating DC faults from rectified loads like VFDs, switching power supplies, or LED drivers.

Temperature range and mounting

The IP20 rating applies only when the distribution board is installed and conductors are connected — this is a panel-internal device, not for wet or outdoor locations.
