Schneider Electric BJA36110 Molded Case Circuit Breaker

Schneider Electric's Square D PowerPact BJA36110 Molded Case Circuit Breaker is a 110 A, 3-pole MCCB in the PowerPact B family, engineered for 600Y/347 VAC systems with an interrupting rating of 25 kA and I-Line bus connections. This thermal-magnetic breaker carries an 80% continuous-load rating, making it suitable for distribution panels and industrial enclosures that require reliable protection for three-phase circuits up to 110 A. As part of the PowerPact B frame, the BJA36110 delivers compact, robust overcurrent protection designed for commercial and light industrial installations where fast fault interruption and consistent trip performance are essential. Typical applications include panelboards, switchboards, and other 3-phase distribution assemblies operating at 600Y/347 VAC, where equipment protection, safe shutdown, and coordination with upstream protection are important. The 110 A rating, combined with 25 kA interrupting capacity, supports protection of moderately sized feeders in moderately heavy-duty electrical systems, while the I-Line design simplifies mounting and connections in standard electrical enclosures.
