ABB Monitoring Relay Single and Three Phase SPST Contact DIN Rail Mount 460V AC 1SVR550871R9500

ABB 1SVR550871R9500 Monitoring Relay is engineered for both single and three phase electrical systems with a supply voltage rating of 460V AC. This device provides crucial phase failure detection and voltage monitoring to ensure electrical system safety and reliability in industrial environments.

The relay features an SPST (Single Pole Single Throw) contact configuration and mounts seamlessly on DIN rails using a snap-on mechanism that requires no additional tools, facilitating fast and secure installation. Screw terminals secure wiring connections robustly, reducing risk from vibration or mechanical movement.

Designed to monitor voltages from 320 to 460V AC withstanding surge voltages up to 4kV, the relay significantly reduces the risk of power faults, protecting connected equipment. Its operating temperature range spans from -20°C to +60°C, allowing use in diverse environmental conditions.

A visible LED status indicator enables quick operational checks without interrupting system functionality. Measuring a compact height of 78mm, length of 78.5mm, and width of 22.5mm, its space-efficient design is ideal for electrical cabinets and control panels.

Certified to CSA, UL, CE, and RoHS standards, this product upholds high quality and compliance expectations for safety and environmental concerns. The CM-PVE series relay is made in Bulgaria, representing trusted manufacturing standards.

Typical applications include server management systems, power distribution networks, small parts manufacturing, and other industrial or commercial installations requiring vigilant electrical phase monitoring. The relay draws its operating power directly from the circuit it monitors, eliminating the need for an additional power supply.
