Square D EDB24035 Molded Case Circuit Breaker

This E-frame breaker is designed exclusively for bolt-on installation in Square D NF series panelboards. It is not compatible with NQ, I-Line, or QO load centers.

The difference is their interrupting capacity at 480Y/277VAC. EDB breakers are rated at 18kAIC, EGB breakers at 35kAIC, and EJB breakers at 65kAIC. All three share the same physical footprint and mount in NF panelboards.

Yes, standard EDB thermal-magnetic breakers without specific line and load markings are suitable for reverse-feed applications.

Yes, Square D EDB circuit breakers are HACR rated, making them suitable for use with heating, air conditioning, and refrigeration equipment.

No, the standard EDB24035 provides only thermal-magnetic overload and short-circuit protection. For equipment ground fault protection, a breaker with an EPD suffix is required.

When the breaker trips due to an overload or short circuit, the handle snaps to a center position and a red indicator appears. This allows for rapid identification of the tripped circuit in a crowded panelboard.

Torque specifications depend on the exact wire gauge and material being installed. Always apply the specific torque value printed directly on the breaker label to ensure a secure and code-compliant termination.
