The Protech Engineering & Controls Pvt. Ltd. VR3-4R is a general-purpose voltage monitoring relay for offering secure protection of electrical systems. It operates from a source voltage of 230V AC and a sensing voltage of 415V, providing efficient voltage monitoring and delay control in industrial use. It has two programmable ranges: Range A (U/V) 70 - 95% for under-voltage protection and Range B (O/V) 105 - 120% for over-voltage protection. It is built with both on delay and off delay capabilities, each of which are programmable to 10 seconds, which ensures smooth operation and avoids nuisance tripping. The contacts sustain 5A resistive load at 230V AC and 28V DC, thus being ideal for controlling machinery and circuits. The VR3-4R is light, weighing only 470 grams, and is compact, reliable, and easy to implement in electrical systems, providing high performance for voltage regulation.
