Nichiyu Electric Manufacturing Co., Ltd. Complete Electromagnetic Circuit Breaker for Wiring (MCCB) New-FM Series 100AF 'NS100AH / MNS100AH'

The "New-FM Series (NS100AH / MNS100AH)" from Nichiyu Electric Co., Ltd. is a fully electromagnetic circuit breaker (MCCB) that employs an oil dashpot method for overcurrent detection and disconnection, without using bimetal (thermal) mechanisms. 【Ideal for the following challenges and applications】 Experiencing significant temperature rises within control panels, leading to malfunctions (unwanted trips) of thermal breakers. Wanting to ensure reliable overload and short-circuit protection while preventing trips caused by the starting current of induction motors. Main and branch protection for equipment requiring stringent protective coordination, such as inverter circuits and power supplies. Stable operating characteristics unaffected by ambient temperature Due to its fully electromagnetic design, there is minimal variation in operating characteristics (derating) due to changes in ambient temperature. It maintains the designed tripping characteristics even in sealed panels that tend to become hot or in harsh environments. Immediate re-engagement after tripping is possible Unlike thermal types, there is no need to wait for the bimetal to cool down, allowing for quick re-engagement and recovery after the cause of the overload trip has been removed. *For detailed operating characteristic curves, dimensional diagrams, rated breaking capacities, and other technical materials, please download and view the catalog PDF.
