ABB S272K8A DIN Rail 2 Pole Circuit Breaker 1 Phase

ABB S272K8A is a two-pole DIN-rail miniature circuit breaker (MCB) designed for single-phase protection in 35 mm DIN rails. It is rated 8 A and configured for 480Y/277 VAC operation, featuring a K-type trip characteristic (K-Curve). The device is UL489-listed and intended for easy clip-on installation on standard DIN rails (TH35-15) in electrical panels. With two poles, it protects both conductors in a single-phase circuit, making it suitable for panelboards, distribution boards, and automation cabinets that operate from 480/277 V systems. The compact 2P package saves panel space while delivering overcurrent protection for modest-load circuits and control circuitry.
