The short-time delayed characteristic (selective / S-type) introduces a deliberate trip delay, so it can be used downstream of a time-delay RCCB or upstream of instantaneous RCCBs without nuisance tripping from transient leakage. The 100 mA sensitivity is sized for sub-distribution or main incomer duty where a 30 mA device would trip on normal cable leakage; it is not for socket-outlet final circuits requiring 30 mA personal protection. The IP20 rating applies with conductors connected inside a distribution board — the RCCB itself is not sealed against moisture ingress; it belongs in a panel with at least IP2X enclosure protection. ## Panel integration Snap-on DIN rail mount (EN 60715), 72 mm wide (4 modular width units), 70 mm installation depth. Mounting position is unrestricted — the device operates in any orientation. The finger and back-of-hand safe touch protection meets the requirements for live-part shielding inside a distribution board.","metaTitle":"Siemens 5SV3444-6LB01 SENTRON RCCB, 40A 100mA, 4P Type A","metaDescription":"Siemens SENTRON 5SV3444-6LB01 RCCB, 4-pole, Type A, short-time delayed, 40 A, 100 mA, 230/400 V AC, 10 kA SCCR.
