ABB S272-K1.6 Circuit Breaker

ABB S272-K1.6 is a two-pole miniature circuit breaker rated for 1.6 A, designed to protect AC distribution circuits in industrial and commercial equipment. This DIN rail‑mountable device protects circuits up to 480 VAC (commonly listed as 277/480 VAC), making it suitable for panel boards, control cabinets, and machine feeds where compact, reliable overcurrent protection is needed. The K-curve trip characteristic of the S272-K1.6 provides a faster response to moderate inrush currents typical of transformer and motor loads while avoiding nuisance trips on normal operation. As part of ABB's S272 family, this 2P breaker offers a compact, robust protection solution for low-current circuits in automation and power-distribution systems, and for retrofit into existing ABB installations. If you are selecting a replacement, confirm regional version and mounting style with ABB or an authorized distributor to ensure proper fit and electrical compatibility.
