TFL236150 - 150Amp Circuit Breaker

TFL236150 - 150 Amp Circuit Breaker

The TFL236150 molded case circuit breaker is a 3-pole, 150-amp current limiting circuit breaker designed for use in your commercial and industrial electrical distribution systems where dependable circuit protection is required. Built with a non-interchangeable trip unit, this breaker helps you provide consistent overcurrent and short-circuit protection while maintaining the original factory configuration. Its current-limiting design helps you reduce the amount of fault energy that passes through the electrical system during short-circuit conditions, supporting the protection of connected equipment and electrical infrastructure.

Rated for operation in systems up to 600 VAC, the TFL236150 features interrupting capacities of 25kA at 600VAC, 65kA at 480VAC, and 100kA at 240VAC, making it suitable for a wide range of power distribution applications. The breaker includes load-side lugs for convenient installation and is engineered for compatibility with equipment designed to accept Type TFL circuit breakers. Built to last and intended as a form, fit, and function replacement, this breaker can help you to maintain the integrity and operation of existing electrical systems.
