Schneider Electric EGB24030 Bolt-On Circuit Breaker

Schneider Electric's Square D EGB24030 bolt-on mini circuit breaker is an E-Frame, 2-pole device rated for 30 A in 480Y/277 VAC systems, with a maximum interrupting capacity of 65 kA at 480 V. It is designed for bolt-on mounting in NF panelboards, providing secure, bolted-in installation rather than a plug-on configuration. This 2-pole breaker protects both hot legs of a 480Y/277V circuit and is TAA-compliant for projects requiring Trade Agreements Act-compliant components. As part of the E-Frame family, the EGB24030 matches Square D bolt-on breakers used in compatible panelboards, enabling straightforward replacement or expansion of existing electrical distributions. Suitable for commercial and light-industrial applications, it covers feeders and branch circuits in higher-voltage 480Y/277V systems where reliable isolation of faults is critical.
