Square D EJB34110 is a three-pole molded case circuit breaker designed to provide reliable overcurrent protection for three-phase electrical systems. It features a 110A current rating and a 480V AC voltage rating, with a 65kA interrupting capacity at that voltage for robust short-circuit protection. The breaker's compact dimensions of 143.76 mm H x 74.68 mm W x 102.87 mm D and 3.472 lb weight facilitate installation in NF panelboards using its bolt-on connection, and it operates across a wide temperature range from -25°C to 70°C. Certified to cULus standards, this thermal magnetic breaker provides both long-time and instantaneous trip functions for coordinated protection. It is typically applied in industrial and commercial power distribution for protecting feeders and branch circuits compatible with wire sizes from AWG 12 to 2/0 aluminum or AWG 14 to 2/0 copper.
