Description
Operating at up to 600VAC, this 100A, three-pole molded case circuit breaker is designed for heavy-duty commercial power distribution. It utilizes a proven thermal-magnetic trip mechanism to handle overloads and short circuits. This legacy component bolts into Siemens P4, P5, and classic ITE FC/S-Series panelboards. For facilities upgrading their infrastructure, the JD63B100 is the recommended replacement. It includes standard line and load lugs and supports a 35kAIC rating at 480V.Specifications
