Description
Serving as a crucial component for older commercial systems, this 20A, three-pole MCCB delivers reliable long-time and instantaneous protection. The bolt-on configuration fits perfectly into classic Westinghouse panelboards. It serves as a seamless drop-in solution that eliminates the need for retrofit kits, and crosses over to the EHD3020. With a 14kAIC rating at 480Y/277VAC, this E-frame unit includes a fixed thermal-magnetic trip.

    Fast reliable service, reasonable prices

    I recently ordered the incorrect breakers for a job, but I contacted Drew at SuperBreakers and he got me the correct breakers shipped out that day, which I received the next day. He sent me a label to send the wrong breakers back, and I was quickly refunded a restocking fee that I incurred for my mistake. I was able to get the breakers installed, and the power running to meet the deadline. Not to mention, the price was better than I found elsewhere. Thanks Drew!

    I would definitely recommend this company if you need fast, reliable service for your electrical product needs. And I'm sure I will use them again.

    Thank you SuperBreakers! Nice job Drew!
