THQC32045WL - 45Amp Circuit Breaker

THQC32045WL - 45 Amp Circuit Breaker

The THQC32045WL is a 45-amp, 3-pole molded-case circuit breaker designed to protect your three-phase electrical circuits from overloads and short circuits. Part of the Q-Line family, this breaker is commonly used in commercial and industrial electrical systems where dependable circuit protection is essential. Its internal common trip design ensures that all three poles open together whenever a fault occurs, helping you to prevent equipment damage and improve system safety.

With a 10kA interrupting rating at 240VAC, the THQC32045WL is designed to handle fault conditions while maintaining reliable operation under normal electrical loads. The cable-in/cable-out lug configuration allows for straightforward field installation, making it a practical choice for panelboard and distribution applications. Its compact molded case construction also helps you maximize available space inside electrical equipment.
