EJB34030SA

Square D EJB34030SA 30A 3-Pole E-Frame Miniature Circuit Breaker, 480Y/277V AC, 65kA, Bolt-On, Shunt Trip

The Square D EJB34030SA is a Type EJB E-Frame miniature circuit breaker rated 30 A across three poles at a maximum operating voltage of 480Y/277 V AC, with a thermal-magnetic trip unit and a factory-installed shunt trip. Breaking capacity is 65 kA at 480Y/277 V AC and 100 kA at 120/240 V AC, and the device carries cULus certification with HID and HACR ratings.

Bolt-on construction locates the EJB34030SA in Square D NF panelboards, where the three-pole body and its shunt trip accessory together require four pole spaces. Aluminum lugs terminate AWG 12 to AWG 6 aluminum or AWG 14 to AWG 6 copper at 30.09 lbf-in.
