Altech E305318 Two-Pole Branch Circuit Breaker

The Altech E305318 is a UL489-listed two-pole miniature molded-case circuit breaker (D-Trip) from Altech's L-Series, designed to protect two live conductors in industrial panels and control cabinets. It provides branch-circuit protection with amperage ratings from 0.2 A to 63 A on 240 VAC systems and from 0.2 A to 32 A on 480Y/277 VAC systems, enabling selection to match motor loads, heaters, and other two-pole circuits. With a 10 kA short-circuit current rating, it can interrupt fault currents on both 120/240 VAC and 480Y/277 VAC distributions. The device occupies two poles and is UL489-listed for standard electrical protection in commercial and industrial environments. The E305318 is part of Altech’s L-Series family, which includes other 2-, 3-, and 4-pole configurations, offering consistent mounting footprints and trip characteristics within a single panel design. Typical applications include safeguarding motor control circuits, pumps, fans, and other two-pole loads in panels where space efficiency and UL489 compliance are essential.
