TFJ236150 **Older Style** - 150Amp Circuit Breaker

TFJ236150 **Older Style** - 150Amp Circuit Breaker

The TFJ236150 is a 150-amp, 3-pole molded case circuit breaker built on the F225 frame and designed for use in your commercial and industrial power distribution systems. This breaker features an older-style black face and a non-interchangeable thermal-magnetic trip unit, making it a practical replacement for existing installations that require the same configuration and ratings. Load-side lugs are included to simplify installation in compatible equipment.

Thermal-magnetic protection combines two methods of circuit protection in a single unit. The thermal element responds to sustained overload conditions, while the magnetic element reacts to higher fault currents associated with short circuits. This design helps you protect conductors and connected equipment from damage while maintaining reliable operation within the system's intended ratings.

Whether you installed it in a switchboard, panelboard, or industrial distribution system, the TFJ236150 is intended for applications where maintaining compatibility with existing electrical equipment is important. Its construction reflects the durability expected of molded case circuit breakers used in demanding commercial and industrial environments.
