MCCB 630H Frame Electronic Trip, 400A-630A, 50kA - 3 Pole & 4 Pole | Onesto KCM5

The Onesto KCM5 630H 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 on industrial and heavy commercial distribution boards. Available in both 3 Pole and 4 Pole configurations, adjustable across 400A to 630A.
