Siemens Industrial Controls 3RV29011E Auxiliary Switch 1 NO 1 NC Contact Block

The Siemens 3RV29011E is an auxiliary contact block designed for use with Siemens 3RV2 series motor protection circuit breakers. This side-mounted auxiliary switch provides one normally open (1 NO) and one normally closed (1 NC) contact for remote signaling, interlocking, and control circuit applications.

Key Features:

• Single normally open (NO) and single normally closed (NC) contact configuration
• Designed for easy snap-on installation to 3RV2 circuit breakers
• Provides electrical status indication and remote control capability
• Rated for control circuit voltages up to 690V AC
• Compact design allows multiple auxiliary blocks to be mounted side-by-side
• Conforms to IEC standards for industrial control equipment

This auxiliary switch block enables motor control systems to integrate circuit breaker status monitoring into PLC systems, control panels, and automated machinery. The dual contact configuration provides flexibility for both alarm signaling and interlock safety circuits.
