MCCB 250H Frame Electronic Trip, 100A-250A, 35kA - 3 Pole | Onesto KCM5

The Onesto KCM5 250H Frame Electronic Trip MCCB uses an electronic trip unit instead of adjustable thermal-magnetic, giving a single wide current-adjustment range across the frame's full rated capacity rather than several narrow bands. It is suitable for electricians, panel builders, contractors and maintenance teams who want one breaker that covers a broad current window in the 250H frame size. Available in 3 Pole configuration, adjustable across 100A to 250A.
