Square D BDA260402 PowerPact B Circuit Breaker – 2 Pole – 40A – Thermal Magnetic – I-Line – LI Protection

The Square D BDA260402 is a PowerPact B-frame molded case circuit breaker designed for dependable overcurrent protection in commercial and industrial electrical distribution systems. Manufactured by Schneider Electric, this 2-pole, 40A breaker utilizes thermal-magnetic trip technology to provide reliable Long-Time and Instantaneous (LI) protection against overloads and short circuits.

Engineered for installation in Square D I-Line panelboards and switchboards, the BDA260402 features an integrated I-Line mounting configuration for fast and secure installation. It serves as a direct replacement for legacy FA26040 circuit breakers while maintaining compatibility with existing AC phase-connected systems. The breaker incorporates current-limiting technology and a visual trip indicator to enhance system protection and simplify maintenance.
