Square D EJB36100 is a 3-pole molded case circuit breaker from the EJB Series, designed for overcurrent protection in commercial and industrial power distribution systems. It is rated for 600V AC, 100A continuous current, and provides LI (Long-Time and Instantaneous) trip functions for thermal-magnetic protection. This bolt-on breaker measures 5.66 in x 2.94 in x 4.05 in (143.76 mm x 74.68 mm x 102.87 mm), weighs 3.62 lb, and is constructed for use in NF panelboards with a 104 °F (40 °C) ambient temperature rating. It is cULus certified and offers a 65kA interrupting capacity at 480V, three-phase, with wire size compatibility from AWG 14 to AWG 2/0 copper or AWG 12 to AWG 2/0 aluminum. Typical applications include branch circuit protection in industrial control panels, switchboards, and power distribution systems requiring reliable overcurrent interruption.
