ABB 3 Phase SPDT Monitoring Relay DIN Rail Mount 24 V DC 24 V AC 240 V AC 1SVR740740R0300 CM-TCS.13P

ABB 1SVR740740R0300 CM-TCS.13P Monitoring Relay is a high-precision 3 Phase SPDT relay designed for temperature monitoring applications with a robust DIN Rail mount and screwless terminal connection. It supports supply voltages of 24 V DC, 24 V AC, and 240 V AC, suitable for diverse electrical environments.

This relay is engineered for use with PT100 sensors to monitor temperature accurately. It can detect over-temperature, under-temperature, or temperatures within two set thresholds, providing instantaneous switching outputs when conditions deviate from preset parameters. The front-face LEDs clearly display operational states, enhancing visual diagnostics.

The device features reliable short circuit monitoring and wire break detection to ensure safety and prevent malfunctions during operation. It is available with two terminal options: traditional screw connections or Easy Connect push-in for efficient wiring.

Designed for industrial and commercial electrical automation, control panels, and HVAC systems, the monitoring relay complies with fire protection standards with housing material rated UL 94 V-0. The dimensions (length 103.7 mm and height 85.6 mm) allow for compact installations on DIN Rails, saving panel space.

The IP50 and IP20 ratings provide protection against dust ingress, suitable for typical electrical enclosure environments. This product does not carry specific standards or approvals but commands reliability from ABB’s trusted engineering.
