Description
A drop-in replacement for aging infrastructure, this 250A MCCB utilizes integrally fused Amp-Trap limiters to provide superior current-limiting performance. It installs into legacy ITE and Siemens switchboards or motor control centers. For modern upgrades, it is replaced by the CJD63B250, which requires a retrofit kit for proper installation. Equipped with thermal-magnetic protection, it handles 600VAC systems while maintaining a 100kA short-circuit current rating.
