The Siemens 3VA5330-5EF31-0AA0 is a heavy-duty molded case circuit breaker (MCCB) from the SENTRON 3VA53 frame family, designed for commercial and industrial power distribution systems. Built on the robust 3VA53 frame, this 300A, 3-pole breaker provides reliable long-time and instantaneous (LI) protection using a TM240 thermal-magnetic trip unit with adjustable thermal and adjustable magnetic settings. It delivers dependable fault interruption performance for high-energy electrical systems and is suitable for feeder and distribution applications in industrial installations.

This breaker is designed for Siemens 3VA panelboards and switchboards and can be installed in Siemens P3, P4, and P5 systems. With appropriate mounting hardware, it serves as a replacement for legacy JD63B300 breakers, making it suitable for retrofit and upgrade applications in existing infrastructure.
