This ABB 2CSF204201R3630 is a 4-pole residual current circuit breaker rated at 63 A, designed for DIN rail mounting in distribution boards. It operates at 50 Hz with a rated insulation voltage of 500 V and an IP2X touch protection rating, meaning it's safe for exposed installation behind a panel door. The 69 mm depth keeps it within standard enclosure depth limits. Current production stage means no last-time-buy urgency – this is a live line. Quote-to-order lead times apply; let's get an RFQ if you need a specific quantity for a BOM freeze.
What the ratings mean for your fit
63 A continuous rating for feeder circuits. 4-pole configuration for three-phase plus neutral. IP2X protection; mount on DIN rail (70 mm width).
Lifecycle stage is current – no signs of phase-out or obsolescence. This is not a surplus play; it's a standard-line RCD you can spec into a design and expect multi-year availability. If you're sourcing for a long-run BOM, this part is stable. RFQ only for firm quantities; we quote against scheduled demand.
