Tomzn TOVPD3-VAYA 3 Phase Auto Phase Selector Voltmeter Adjustable Over and Under Voltage Protection

Key Features

Auto Phase Selector: Automatically selects and balances the appropriate phase to prevent damage caused by unbalanced or faulty conditions.

Adjustable Over and Under Voltage Protection: Cuts off the circuit when voltage exceeds preset over or under voltage limits, ensuring equipment safety.

Asymmetry Trip Delay: Incorporates a 10-second delay for asymmetry to prevent unnecessary disconnections and improve system stability.

High Measurement Accuracy: Ensures precise voltage monitoring with an accuracy of ≤1% across the entire range.

Durability: Rated for 100,000 electrical and mechanical operations, offering long-lasting reliability for demanding environments.

Indoor Use Design (IP20 Protection): Protects against large solid objects and is ideal for dry, indoor installations.
