TJD432250 - 250Amp Circuit Breaker

TJD432250 - 250 Amp Circuit Breaker

When your electrical systems need dependable overcurrent protection, the TJD432250 molded case circuit breaker is a practical fit for many commercial and industrial applications. This 250 amp, 3-pole breaker is part of the Q-Line series and is designed for use in compatible bolt-on distribution equipment. Its internal common trip mechanism helps disconnect all poles together during overload or fault conditions, helping protect connected equipment and wiring from damage.

The breaker includes load-side lugs, which can help you reduce installation time during maintenance or replacement work. With a 22kA interrupting rating at 240VAC, the TJD432250 is commonly used in facilities that rely on steady, consistent power distribution. Because it is HACR rated, it is also suitable for heating, cooling, and refrigeration systems found in commercial buildings and industrial environments.

Built with a molded case housing designed for long service life, this breaker is often used as a form, fit, and function replacement in existing systems where equipment compatibility matters. Its bolt-on design supports secure installation in matching panelboards and electrical assemblies without unnecessary modifications.
