Notice of Production Discontinuation for 60A Frame (January 26, 2023) 1. Discontinued Models Product Name Model Number Wiring Circuit Breaker (General Purpose Series) NS62A NS63A NS62AH NS63AH Wiring Circuit Breaker (Motor Breaker) MNS63A MNS63AH 2. Recommended Alternative Models: 100A frame circuit breakers with a rated current of 60A are recommended for each circuit breaker. 3. Timing of Production Discontinuation: Until delivery on September 30, 2023 (Last order acceptance period: Orders received by June 30, 2023) For any questions or inquiries, please contact the Sales Department of Nikkoh Electric Manufacturing Co., Ltd. at (044-455-1211). This is the "New-FM Series" 60AF wiring circuit breaker from Nikkoh Electric Manufacturing Co., Ltd. It features a fully electromagnetic design using an oil dashpot, ensuring reliable protection that is not affected by ambient temperature and allowing for immediate re-engagement after a trip. In addition to the standard breaking capacity types (NS/MNS), we also offer high breaking capacity types (NS-AH/MNS-AH) that are compatible with higher power sources and large capacity systems.

basic information
High reliability through completely electromagnetic (oil dashpot type) design Unlike bimetallic (thermal) types, it utilizes viscous fluid and magnetic attraction within a sealed cylinder. It exhibits stable trip characteristics unaffected by heat generation in the control panel or external temperatures (low to high). Minimizing recovery downtime No waiting time for bimetal cooling. Once the cause of the anomaly is resolved, it can be reset immediately even right after a trip. Flexible lineup from standard type to high breaking capacity type (AH) You can choose between standard type (NS) and high breaking capacity type (NS-AH) according to the estimated short-circuit current of the system, contributing to the optimization of equipment design. Wiring protection and motor protection tailored to applications Wiring protection (NS60A / NS60AH): Overload and short-circuit protection for branch and trunk circuits. Available in 2P and 3P configurations. Combined motor protection (MNS60A / MNS60AH): Does not operate during motor startup inrush current, accurately disconnecting overload, binding, and short-circuit conditions.

Applications/Examples of results
High-density sealed control panels and outdoor power panels (environments where the interior tends to become high temperature) Locations with large short-circuit currents, such as directly under large-capacity transformers or factory main lines (AH type with high breaking capacity is optimal) FA and automation lines where frequent line stoppages are to be avoided (maintaining operational efficiency through immediate recovery) Machine tools, power panels, distribution panels, sealed control panels, conveying equipment, three-phase motor circuit protection
