Setra CSCG-A-2-125-NN Power Relay

The Setra CSCG-A-2-125-NN is a high-performance adjustable setpoint current switch designed for precision monitoring in HVAC automation and building management systems (BMS). Engineered for solid-core current sensing, this device features a 1.25 Amp setpoint, providing an accurate on/off status signal for motors, pumps, and fans. The integrated LED status indicator offers immediate visual feedback for field technicians, facilitating rapid troubleshooting of under-current or over-current conditions. Unlike models with integrated power relays, the CSCG-A-2-125-NN is optimized for dedicated sensing applications where a snap-on power relay is not required. It functions as a reliable digital output sensor, ensuring the controller receives a clean signal when current exceeds the calibrated threshold. This unit is essential for preventative maintenance, providing a dependable alternative to differential pressure switches for belt-loss detection and motor status verification in critical air handling applications.

• Precise Current Monitoring: Features a 1.25 A adjustable setpoint for tailored sensitivity across various inductive loads.
• Enhanced Visual Diagnostics: High-visibility LED indicator simplifies setup and confirms device state and setpoint crossing.
• Solid-Core Reliability: Rugged solid-core design ensures long-term stability and accurate magnetic induction sensing without moving parts.
• Seamless System Integration: Compatible with DDC controllers and BAS platforms for automated fault detection and equipment monitoring.

What is the primary application for the 1.25 A setpoint?
This specific setpoint is ideal for monitoring fractional horsepower motors and indicating status for small exhaust fans or circulator pumps where detection of precise current draw is vital.

How does this model handle setpoint adjustment?
The multi-turn potentiometer allows for fine-tuning the trip point, ensuring the switch ignore inrush current while providing accurate feedback during steady-state operation.

Can this device be used for belt-loss detection?
Yes, by calibrating the current switch to trigger on the drop in amperage that occurs when a belt breaks or slips, technicians can automate system alarms through the BMS.
