The 4-pole configuration (3 phases + neutral) means it fits three-phase four-wire systems; the neutral pole opens with the phases, so the circuit is fully isolated when the breaker trips — required for TT or TN-S earthing systems where the neutral is not bonded to the protective earth downstream. ## DIN rail mount, IP2X — panel integration Snaps onto a standard 35 mm DIN rail (EN 60715) inside the distribution board or sub-panel — the 70 mm width occupies 4 modular units (4 x 17.5 mm), so it replaces a standard 4-pole MCB footprint without re-drilling the mounting plate. IP2X means the housing is finger-safe — no live parts are accessible through the front vents — but it is not sealed against moisture; install inside a cabinet rated for the environment, not outdoors or in washdown areas.","metaTitle":"ABB 2CSF204401R1400 RCCB, 4-pole, 40 A, 500 V, DIN rail","metaDescription":"ABB 2CSF204401R1400 residual current circuit breaker, 4-pole, 40 A, 500 V insulation, 50 Hz, IP2X, DIN rail mount.
