Schneider Electric EDB34030 Circuit Breaker

Schneider Electric's EDB34030 is a three-pole, 30‑amp miniature circuit breaker (MCCB) in the Square D E‑Frame family, engineered for reliable protection of 480Y/277 VAC three‑phase circuits in commercial and light‑industrial panelboards. It uses a thermal‑magnetic trip mechanism and bolt‑on mounting, enabling accurate response to overloads and straightforward installation in compatible enclosures. The device offers an interrupting capacity of up to 25 kA at 480 V, supporting high fault currents and helping protect conductors and downstream equipment while maintaining selective coordination with other protection devices in the same system. With the E‑Frame form factor and 3P configuration, the EDB34030 is designed to protect three‑phase feeders and branch circuits and is commonly used in panelboard assemblies within Schneider Electric installations. This part is identified by the EDB34030 model number and carries Trade Agreements Act (TAA) compliance where applicable, aligning with procurement requirements for government or commercial projects.
