Quick Summary

NGS212038E molded case circuit breaker protects industrial control panels by delivering reliable overcurrent protection. Engineers often struggle with nuisance trips or miscoordination when protecting high-amp feeders in dense control panels. This unit carries CSA Certified and UL Listed certifications and HACR rating, supporting safe operation for HVAC and other load types. With Series G architecture, this two-pole MCCB offers precise protection up to 1200 A and a 50 kAIC interrupt rating, helping you meet short-circuit withstand and coordination targets. Imperial tapped line and load terminals streamline installation in legacy panels, and the product’s reverse-feed suitability reduces wiring complexity in strategic layouts. These factors translate to faster commissioning and lower lifecycle costs for industrial facilities.
