Schneider Electric EDB36040 3 Pole Circuit Breaker

Schneider Electric's Square D EDB36040 is a 40-amp, three-pole molded-case circuit breaker (MCCB) in the EDB family, designed for use in 600Y/347VAC three-phase distribution. This bolt-on, E-frame device provides thermal-magnetic protection and is intended to interrupt fault currents to safeguard conductors in commercial and industrial panel boards and switchgear. The EDB36040 is configured for three-phase circuits and is designed for installation where a 40-amp protective device is required for 3P feeders, motors, and equipment fed from 600V-class systems. As part of the Square D line, it offers compatibility with Schneider Electric's E-frame enclosures and bolt-on mounting schemes, enabling straightforward replacement or retrofit in existing installations. Its 3-pole construction ensures simultaneous disconnection of all phases, enhancing safety by preventing residual phase connections after a trip. This part number—EDB36040—serves as a precise sourcing reference for distributors and technicians cataloging molded-case breakers in 600Y/347V three-phase distribution networks, and is commonly listed under the official mfg number EDB36040 for retrofit into Square D E-frame bolt-on panels.
