Description
The Siemens 3RV2901-1A is a compact side-mounted auxiliary contact block designed for use with 3RV2 motor protection circuit breakers in sizes S00 to S3. It features one normally open (1 NO) and one normally closed (1 NC) contact, enabling reliable signaling and control functions in motor starter assemblies. With a rated insulation voltage of 690 V and surge resistance up to 6 kV, it ensures safe operation in demanding environments. The unit mounts via plug-in fixing and connects using screw terminals, offering straightforward installation. Its slim 9.5 mm width and IP20 front protection make it ideal for space-constrained control panels while maintaining finger-safe operation from the front.
