It's an instantaneous-trip device — no intentional delay — so it clears ground faults as fast as the waveform allows. Snaps onto standard DIN rail (REG). Depth is 77 mm, installation depth 70 mm. IP20 with the distribution board installed and conductors connected; that's typical for enclosed panel gear, not for open-bay exposure.","metaTitle":"Siemens 5SM3348-6 SENTRON RCCB, 4P, 100A, 30mA, 400V","metaDescription":"Siemens 5SM3348-6 SENTRON RCCB, 4-pole, type A, 100 A rated, 30 mA sensitivity, 400 V AC. 10 kA SCCR.
