Square D EDB24090 Circuit Breaker

Square D by Schneider Electric EDB24090 is a two-pole, 90-amp molded-case circuit breaker in the EDB family designed for 480Y/277 VAC distribution. This bolt-on, thermal-magnetic device delivers 18 kA at 480 VAC, making it suitable for commercial and light industrial panelboards and feeders that may experience high fault currents. Rated for ambient temperatures up to 40°C, the 2P unit provides reliable overload and short-circuit protection in demanding power-distribution environments. As part of the EDB frame, it is intended for bolt-on mounting on compatible Square D enclosures and protects two conductors within a single assembly. Typical applications include feeders and branch circuits in distribution panels, switchgear, and motor control centers that require two-pole protection for high-voltage 480Y/277V circuits. The EDB family is built for consistent trip characteristics and durable construction, and this model specifically offers a 90 A rating at up to 480 VAC, enabling straightforward replacement in existing installations without sacrificing protection or performance.
