Square D BDL36045 PowerPact B Circuit Breaker – 3 Pole – 45A – Thermal Magnetic – Unit Mount – EverLink Terminals

The Square D BDL36045 is a PowerPact B-frame molded case circuit breaker manufactured by Schneider Electric, designed to provide reliable overcurrent protection for industrial and commercial three-phase electrical distribution systems. This 3-pole, 45A breaker delivers thermal-magnetic (LI) protection with fixed Long-Time and Instantaneous trip functions, ensuring dependable performance under overload and short-circuit conditions.

Built as a unit-mount device, the BDL36045 supports flexible installation using DIN rail or back-pan mounting systems. It is designed as a direct replacement for legacy FAL36045 breakers, making it suitable for retrofit applications in existing switchboards. Its EverLink lug technology helps prevent conductor loosening caused by vibration and thermal cycling, improving long-term connection stability.
