Trumbull ATB36015 Molded Case Circuit Breaker

The Trumbull ATB36015 Molded Case Circuit Breaker is a 15-amp, 3-pole device rated for 600-volt three-phase service. Housed in Trumbull’s F-frame molded-case family, it is designed for industrial and commercial power distribution applications where reliable overcurrent protection of feeders and branch circuits is required. With a three-pole construction, it interrupts all three phases simultaneously to help maintain system balance in 3‑phase circuits and protect electrical equipment in panelboards, switchgear, and other distribution gear. The catalog identifier ATB36015 corresponds to a 15 A, 600 VAC molded-case breaker intended for use in demanding environments such as manufacturing facilities, data centers, and large commercial installations where compact MCCB form factors are advantageous. As part of the Trumbull lineup (now part of ABB’s legacy product lines), this breaker reflects the rugged, field-replaceable design typical of MCCBs used in retrofit and new-build panels alike.
