The Selec Voltage Protection Relay 600VPR-310/520 is a high-performance 3-phase, 3-wire voltage monitoring relay designed to ensure electrical system safety and reliability. It monitors critical voltage parameters including under voltage, over voltage, phase sequence, and phase failure, protecting equipment from potential damage caused by electrical anomalies. The relay features an adjustable trip delay timer ranging from 0.2 to 10 seconds, allowing precise control over response time to transient faults. Its intuitive LED indicators display relay status and power availability, enabling easy visual monitoring. The analog display type with three knobs allows straightforward operation and setting adjustments. Engineered for robust operation, it sustains environmental conditions from 0 to 50°C operating temperature and up to 95% non-condensing humidity. Certified with CE and UL compliance, this voltage protection relay is ideal for industrial applications requiring reliable voltage supervision within a supply voltage range of 170 to 290V AC (L-L). The device also features an IP20 degree of protection and pollution degrees of 2 and 3 for PCB and overall product respectively, meeting stringent industrial safety standards.
