Square D CC112.0N Molded Case Circuit Breaker

Square D CC112.0N Molded Case Circuit Breaker is a replacement thermal trip unit from the Square D brand (Schneider Electric) designed for CC112.0-series molded case breakers. The unit uses a melting-alloy thermal element to provide overload protection, with a nominal trip current specified at 61.4–63.5 A and a system voltage rating of 480 V, while the thermal unit itself is rated up to 600 V AC. It protects motors, controllers, and branch circuits against overheating from prolonged overload or locked-rotor conditions, helping prevent damage to equipment in 480 V industrial applications. Common use cases include motor control panels and equipment assemblies where CC112.0 MCCBs are employed; the CC112.0N unit is a compatible replacement component for restoring proper trip characteristics in aging CC112.0 breakers. This CC112.0 thermal unit is documented as rated for up to 600 V AC, aligning with Schneider Electric's CC112.0 MCCB line and commonly stocked in after-market catalogs for maintenance and service of existing panels.
