Rated insulation voltage of 500 V and 50 Hz frequency make it suitable for standard single-phase or two-wire branch circuits in residential and light commercial distribution boards. The DIN rail mount (35 mm width) snaps into standard enclosure rails, and the IP2X finger-safe housing means the live terminals are protected against accidental contact during panel servicing. ## Panel fit and dimensions At 69 mm depth, 35 mm width, and 85 mm height, the 2CSF202101R1400 occupies a single module space on the DIN rail — matching the standard footprint for 2-pole RCCBs in ABB's System pro M compact range. The 2-pole construction switches both line and neutral, which is required for circuits where the neutral is not solidly bonded to earth downstream of the RCD. ## Sourcing and lifecycle Listed as current production by ABB — this is an active catalogue item, not a phase-out or obsolete line. No stock-holding claim is made.","metaTitle":"ABB 2CSF202101R1400 RCCB, 40 A, 2-Pole, DIN Rail","metaDescription":"ABB 2CSF202101R1400 RCD circuit breaker, 40 A rated current, 2-pole, DIN rail mount, IP2X, 50 Hz.
