INS 3P 400A

The Schneider Electric iNS400 is a 3-pole, 400A Intelligent Molded Case Circuit Breaker (iMCCB) from the iNS series. It represents a next-generation platform that integrates advanced protection, precise measurement, and native digital connectivity into a compact and robust device. Unlike traditional MCCBs, the iNS breaker features a built-in intelligence module, transforming it from a simple protective device into a key node in the IoT-enabled electrical distribution system.
