Schneider Electric FH16070A Molded Case Circuit Breaker

FH16070A is a Square D by Schneider Electric molded‑case circuit breaker (MCCB) configured as a single‑pole device rated for 70 amperes at 277 V AC. It belongs to the FH family of molded‑case breakers, a line used for branch‑circuit protection in commercial and light‑industrial electrical panels and distribution enclosures that specify FH‑series breakers. The FH16070A designation identifies a 1‑pole, 70 A breaker intended to interrupt and protect circuits feeding 277 V loads, such as lighting and general receptacle circuits, in appropriate Schneider Electric panel systems. As a component from Schneider Electric (Square D), this breaker is designed for use with compatible FH‑frame enclosures and mounting hardware, following the manufacturer’s installation requirements to ensure proper clearance, alignment, and electrical contact with the busbar. Users selecting this model should verify full compatibility with their panel catalog, including voltage rating, frame type, and mounting arrangement, to ensure reliable overcurrent protection and correct trip operation in 277 V circuits.
