On a 277 VAC line it interrupts faults up to 6 kA; on a 500 VDC circuit it handles 10 kA, covering most industrial control panels and DC distribution. The 2-pole form factor fits a single module width per pole, so it occupies two 18 mm slots in a distribution board.","metaTitle":"ABB S202MUC-K50 MCB 2P K 50 A, DIN Rail","metaDescription":"ABB S202MUC-K50 miniature circuit breaker, 2-pole, K-curve, 50 A, 277 VAC / 500 VDC, 6/10 kA interrupting.
