Nichiyu Electric Manufacturing Co., Ltd. New-FM Wiring Circuit Breaker NY225A (NY202A NY203A) MNY225A (MNY203A)

Stable operating characteristics unaffected by ambient temperature Due to its fully electromagnetic design, there is almost no variation in operating characteristics (derating) caused by changes in ambient temperature. It maintains the designed tripping characteristics even in sealed enclosures that tend to get hot or in harsh environments. Immediate re-engagement after tripping is possible Unlike thermal devices, there is no need to wait for the bimetal to cool down, allowing for quick re-engagement and recovery after the removal of the cause following an overload trip. 225AF lineup selectable by application - NY225A (NY202A / NY203A): Standard type (2-pole and 3-pole) optimal for protecting general lighting and power circuits. - MNY225A (MNY203A): Motor protection type (3-pole) with time-delay characteristics tailored to the starting characteristics of electric motors. Rich array of accessories and options Compatible with various auxiliary devices such as auxiliary switches (AX), alarm switches (AL), voltage release devices (SHT), and undervoltage release devices (UVT), allowing for flexible integration into remote monitoring and control systems. *For detailed operating characteristic curves, dimensional drawings, rated tripping capacities, and other technical materials, please download the catalog PDF for reference.
