Industrial HDA261501NN Molded Case Circuit Breaker

Schneider Electric's Square D PowerPact H-Frame molded case circuit breaker, model HDA261501NN, is a 2-pole device rated for 150 A and 600 VAC, with a maximum 250 V DC rating and I-Line mounting for use in industrial panels. This HDA-series breaker uses a thermal-magnetic trip mechanism to protect feeders from overloads and short circuits, and it carries an interrupting rating of 18/14/20/25 kA depending on the service voltage. Designed for PowerPact H-line installations, the HDA261501NN supports plug-in replacement within compatible H-frame assemblies, enabling straightforward maintenance and upgrades in power-distribution schemes. Applications include motor feeders, mains distribution, and protection of branch circuits in manufacturing, processing, and facility power systems where 150 A at 600 VAC protection is required.
