Selec 900VPR-2-300/600V, Voltage Protection Relay
900VPR-2-300/600V Digital Voltage Protection Relay is a versatile solution designed for comprehensive electrical system protection. It addresses parameters such as Under Voltage, Over Voltage, Under Frequency, Over Frequency, Phase Asymmetry, Phase Failure, and Phase Sequence. Compatible with 3-phase 3-wire and 3-phase 4-wire setups, its 3-digit LCD display provides clear information without backlight.
The relay offers customizable time settings, including Trip Time Delay (0-99.9 sec) and Power ON Delay (2-99.9 sec), with a rapid Response Time of less than 200 milliseconds. With high precision, it maintains a ±1% accuracy for trip voltage, ±0.1Hz for frequency, and ±5% for time settings.
The relay features two changeover output contacts (SPDT) for external system interaction, and it accommodates supply voltages from 280V to 600V AC (L-L) and 160V to 300V AC (L-N). Its compact 35mm size and DIN Rail Mounting ensure easy installation, while CE and UL certifications emphasize its safety and quality compliance
