M9F42120

The M9F42120 from Schneider Electric is a Multi 9™ multistandard protection miniature circuit breaker with 1 pole. This miniature circuit breaker provides protection of equipment or especially sensitive circuits within equipment against electrical threats, including short circuits, overloads and earth leakages. Installation labour and space are both minimized by the modular architecture of the Multi 9™ system. The Multi 9™ C60 circuit breaker provides several features which are important to OEMs such as small, compact size, easy installation on DIN rails, limits let-thru current, resetability, more convenient than fuses, electrical auxiliaries for control and status information, extensive variety of accessories. The potential applications include semi-conductor machines, communication equipment, process control panels, computers, medical equipment, electronic controls, transformers, power supplies and other electrical equipment. It is approved by UL 489, CSA C22.2 No 5 and GB 14048.2.
