TJ236150 - 150A Circuit Breaker

TJ236150 - 150A Circuit Breaker

The TJ236150 circuit breaker is a 3-pole, 150-amp thermal-magnetic breaker designed for you to use in commercial and industrial power distribution systems. Built on the TJ frame platform, this breaker provides overload and short-circuit protection for three-phase electrical applications operating at up to 480VAC. The non-interchangeable trip unit keeps protection settings fixed, making it a suitable replacement option for your compatible existing equipment and panel configurations.

Rated at 14kA interrupting capacity at 480VAC, the TJ236150 is commonly used in distribution panels, switchgear, and feeder circuits where dependable circuit protection is required. Its 40°C rating allows it to operate in higher ambient-temperature environments, often found in mechanical rooms, industrial facilities, and electrical service areas. Load-side terminals are included to support installation and secure conductor connections. With its compact TJ-frame dimensions and durable construction, this breaker is built for long-term use in demanding electrical systems.
