Siemens 3VA9137-0FK35 Door Mounted Rotary Operator

Siemens 3VA9137-0FK35 is a door-mounted rotary operator with an emergency-off function that integrates into Siemens 3VA switchgear, providing a clearly accessible shutdown when the equipment door is opened. It is rated for multiple enclosure types, including NEMA 1, 3R, 12, and 4/4X, and is shipped with a door interlock and a door-opening position accessory for the 3VA51 family. This mechanism offers manual electrical isolation through the door-mounted handle, enabling safe maintenance and rapid de-energization in emergencies. Designed to accompany 3VA51 assemblies, it ensures consistent control accessibility and interlock functionality across the lineup.
