The EJB36110 SQUARE D circuit breaker is a high-performance 3-pole breaker designed for reliable overcurrent protection in electrical systems. With a current rating of 110A and the ability to handle up to 600V, it ensures optimal safety and functionality. Ideal for various applications, it is a trusted choice for commercial and industrial use.
The EJB frame is Square D's 600V-rated bolt-on MCCB series, typically covering the 15A–125A range with a 25kA interrupting rating at 600V. Frames like EDB are generally rated for 480V applications, while larger frames such as FA/FH handle higher ampacities. The EJB36110 is specifically suited for 600V industrial and commercial circuits — always verify the frame and interrupting rating match your panelboard's requirements.
Square D has transitioned many EJB-frame breakers through product line updates over the years, making certain configurations harder to source through standard distribution.

The EJB36110 can serve as either a main disconnect or a branch/feeder breaker in a suitable 600V panelboard or switchboard, provided the equipment is rated and listed for that application. Always verify with your panelboard's documentation or consult a licensed electrician to ensure compliance with CSA/CEC requirements for your specific installation.
