Altech's 2CU05R is a two-pole DIN-rail mounted miniature circuit breaker rated for 480Y/277 VAC, designed to protect two conductors in 1-phase, 3-wire electrical panels. With a nominal current rating of 0.5 A and a C-Trip characteristic, it activates on overcurrent to prevent damage to control circuits in industrial automation setups. This UL 1077 recognized device is part of Altech's R-Series, intended for supplementary protection in 2P, 1-phi applications and mounts quickly to standard 35 mm DIN rails. Common applications include control panels and machine automation where a compact, two-pole device can interrupt two conductors in a single-phase 480Y/277 VAC system.
