Description
Built to support existing industrial infrastructure, the Siemens ET225-3100 handles 100A loads with proven thermal-magnetic trip technology. It delivers reliable circuit protection for commercial applications operating up to 600VAC or 250VDC. This legacy unit mount breaker integrates seamlessly into ITE CDP-7 and Siemens P4, P5, SB1, and SB2 panelboards without modification. For facilities updating their systems, this exact replacement model is officially superseded by the newer JXD63B100.Specifications
