Schneider Electric EDB34110 Molded Case Circuit Breaker

Schneider Electric's Square D EDB34110 molded case circuit breaker is a 110 A, 3-pole unit rated for 480 VAC. Designed as a molded-case circuit breaker (MCCB), it provides overcurrent protection and a safe means to interrupt power in three-phase electrical distribution. The EDB34110 designation identifies a device configured for three-phase service with a 110-amp rating and 480-volt operation, suitable for use in commercial or light-industrial panelboards and switchgear that require compact protection for 480 V circuits. It protects feeders and branch circuits by automatically disconnecting power when fault current exceeds the preset limit, helping prevent damage to conductors and equipment. Use cases commonly include protection of motors, transformers, and other 480 V equipment in electrical assemblies that rely on robust, three-phase protection. Although this description uses the model number and ratings shown, it is suitable for protecting circuits feeding balanced loads in 480 V three-phase systems. The device is designed to interrupt fault currents cleanly and rapidly, limiting exposure of downstream equipment to damaging surges. Typical users include electrical contractors, panel builders, and facilities engineers who install MCCBs in commercial or light-industrial power distribution.
