Siemens Industrial Controls 3RA2811-1CW10 Relay
The Siemens 3RA2811-1CW10 is a specialized S Sirius 3RA28 function module engineered for precise on-delay timing operations within industrial and HVACR environments. Designed to snap directly onto the front of 3RT2 contactors (sizes S00 and S0) and 3RH2 auxiliary contactors, this electronic relay eliminates the need for complex external wiring, significantly reducing assembly time and potential wiring errors in your control cabinet. With a broad control supply voltage range of 24-240V AC/DC and an adjustable time range from 0.05 to 100 seconds, this module provides the versatility needed for staggered motor startups and system protection sequences.
Built with a solid-state semiconductor output, the 3RA2811-1CW10 ensures reliable performance even in high-frequency switching applications where mechanical wear is a concern. The integration of an internal varistor for coil attenuation protects your sensitive control circuits from voltage spikes generated during contactor de-energization. This compact, front-mount timing relay utilizes screw terminals for secure electrical connections and carries an IP20 protection rating, making it a rugged standard for professional electrical contractors maintaining Siemens motor control systems.
Key Benefits:- Direct Contactor Integration: Mounts directly to SIRIUS 3RT20 and 3RH2 frames, saving DIN rail space and simplifying the overall panel layout.
- Universal Voltage Compatibility: Operates seamlessly across a wide 24-240V AC/DC range, reducing the need to stock multiple dedicated voltage relays.
- Integrated Surge Suppression: Built-in varistor provides automatic attenuation of contactor coils, preventing harmful back-EMF spikes.
- Precision Timing: High-resolution adjustment allows for on-delay intervals between 0.05s and 100s, ideal for critical sequencing in air handlers and compressors.
- Which contactors are compatible with the 3RA2811-1CW10? This timing module is specifically designed for Siemens SIRIUS S00 and S0 frame sizes, including the 3RT201, 3RT202, and 3RH2 series.
- Does this relay require a neutral wire for DC operation? No, the electronic timing relay functions with the standard control supply voltage provided across the specified 24-240V range via the screw terminals.
- Can I use this for off-delay functions? No, this specific model is a dedicated on-delay function module. For off-delay requirements, an alternative part number such as the 3RA2812 is required.
