Setra CSCG-A-2-125-R1 Relay

The Setra CSCG-A-2-125-R1 is a high-performance split-core current switch designed for precision monitoring in HVAC automation and industrial control systems. This multi-functional device integrates a clamped current sensor with a snap-on power relay, allowing technicians to facilitate on/off motor status detection and remote equipment control in a single, compact unit. Engineered for versatility, it features an adjustable setpoint ranging from 1.25 to 135 Amps, making it an ideal choice for protecting fan motors from locked rotor conditions or belt slippage. The induced power design ensures the sensor remains self-powered via the monitored conductor, while the 24V AC/DC command relay enables seamless direct-drive motor control. With its secondary LED indication for both switch and relay status, this device provides immediate visual confirmation of operational health, streamlining field troubleshooting and preventive maintenance protocols. Utilize this robust solution to ensure reliable proof of operation for pumps, lighting loads, and critical air handling units.

• Streamlined Installation: The split-core design allows for fast clamping onto existing conductors without disconnecting high-voltage wiring.
• Dual-Function Monitoring: Combines digital current sensing and a command relay to reduce enclosure footprint and wiring complexity.
• Precision Calibration: The multi-turn adjustable setpoint ensures accurate trip points for varying loads, from small exhaust fans to large blowers.
• Visual Diagnostics: Integrated status LEDs allow for rapid identification of current status and relay actuation during commissioning.
• Self-Powered Operation: Sensing circuitry is magnetically induced from the line, eliminating the need for external power to the sensor itself.

How do I calibrate the setpoint for an under-current alarm?
To detect mechanical failures like belt loss, turn the setpoint screw clockwise until the LED changes state, then back off slightly to create a stable deadband that prevents nuisance tripping.

Can this relay be used with Variable Frequency Drives (VFDs)?
The Setra CSC Series is optimized for 50/60 Hz applications. When used on the load side of a VFD, ensure the frequency remains within the rated range for accurate induction and switching.

What is the maximum load the snap-on relay can handle?
The integrated SPST relay is rated for 10A at 260V AC or 5A at 30V DC, providing sufficient capacity for most starter coils and small motorized loads.
