Square D EGB24030 Circuit Breaker 30A 480V 2 Pole

Product Description

The SQUARE D EGB24030 is a 2-pole miniature circuit breaker rated for 30 amps at 480Y/277 volts, designed for bolt-on panel installation. It delivers a 35 kA interrupting capacity, making it suitable for commercial and industrial distribution panels where high fault-current ratings are required. The lug terminal connection type accepts 12 and 14 AWG conductors. This breaker provides overcurrent and short-circuit protection for branch circuits and is installed by licensed electricians working on low-voltage distribution systems.

The EGB24030 is intended for use in commercial and light industrial electrical distribution panels operating at 480Y/277 volts. Typical applications include branch circuit protection in multi-story buildings, manufacturing facilities, and other settings where a bolt-on breaker in a matching loadcenter or panelboard is required. The 2-pole configuration handles two-phase branch circuits in a 480Y/277-volt system.
