It is an instantaneous (non-delayed) unit with a fixed fault current — no adjustment on the dial. The 30 mA threshold means it provides supplementary protection against direct contact in circuits serving socket outlets or general-purpose loads, while the Type A designation covers pulsating DC fault currents up to 6 mA superimposed on the AC waveform, which standard AC-only RCDs miss. The 70 mm installation depth matches the standard SENTRON MCB/RCD enclosure depth, so it sits flush in a distribution board without protruding past the cover. The IP20 rating applies once the distribution board is installed with conductors connected; the device itself is not sealed against washdown or dust ingress. ## Voltage and environmental limits Operating frequency is 50 Hz only. Pollution degree 2 (non-conductive pollution that may become temporarily conductive due to condensation) covers typical residential and commercial panel environments.","metaTitle":"Siemens SENTRON 5SM2346-6 RCD Unit, 4-Pole, 63 A, 30 mA, Typ","metaDescription":"Siemens SENTRON 5SM2346-6 RCD unit, 4-pole, Type A, 63 A, 30 mA, 400 V AC.
