Square D BJA36030 PowerPact 3 Pole Circuit Breaker

Square D PowerPact BJA36030 is a three-pole molded-case circuit breaker in the PowerPact B-frame family. It is rated 30 amps for a three-phase circuit and is suitable for 600Y/347 VAC systems, using an I-Line plug-in connection with ABC phase arrangement for easy installation in compatible panels. The device is thermomagnetic with long-time and instantaneous trip functions and has a non-interchangeable trip mechanism. It carries a 25 kA interrupting rating at 600Y/347 VAC, which specifies its fault-current handling capability. The BJA36030 provides load-side mechanical lug terminals, simplifying field wiring. This MCCB is intended for use in PowerPact B-frame switchgear and panelboards where a 30 A, 3-pole protection device is required, aligning with upstream protection and downstream equipment coordination in industrial or commercial installations. As part of Square D's PowerPacT PowerPact line, the BJA36030 is designed to fit installations that use I-Line plug-in breakers and non-interchangeable trip units, ensuring consistent trip characteristics across the B-frame family.
