This is the part you reach for when you need a standard 40 A branch-circuit protector in a 3P DIN-rail footprint for a distribution board or sub-panel. At 40 A per pole, this covers feeder circuits for lighting, small motor groups, or transformer primaries within the 10 kA prospective fault level. The 440 V AC rating handles line-to-line voltages common in three-phase panels.","metaTitle":"ABB 2CDS273001R0405 S203M-B40 MCB, 3P 40A Curve B, 10 kA","metaDescription":"ABB System Pro M Compact S200M MCB, 3P, 40A Curve B, 440V AC, 10 kA breaking capacity.
