Square D BDL26040 PowerPact B Circuit Breaker – 2 Pole – 40A – Thermal Magnetic – Feed-Thru – 600V Class

The Square D BDL26040 is a PowerPact B-frame molded case circuit breaker manufactured by Schneider Electric, designed for reliable overcurrent protection in commercial and industrial electrical distribution systems. This 2-pole, 40A breaker provides thermal-magnetic protection with Long-Time and Instantaneous (LI) tripping to safeguard circuits against overloads and short-circuit faults.

Built for flexible installation, the BDL26040 features a feed-thru configuration and supports both traditional back-pan mounting and DIN rail installation. Its compact B-frame design allows efficient use of panel space while maintaining strong interrupting performance. The breaker includes EverLink lug technology on termination points, helping ensure consistent torque retention and long-term connection reliability.
