Questions about Voltage & Current Protection Relays
What should I check before selecting voltage & current protection relays?
A monitoring relay does not necessarily interrupt load current itself. Confirm the external contactor or breaker arrangement and the required protection functions.
What information is needed to quote voltage & current protection relays?
Provide single/three-phase supply and measurement range; over/under voltage, current, phase-loss or sequence function; trip threshold, delay and reset arrangement; output contact duty and CT requirement. Include the quantity, requested make or existing reference and delivery PIN code.
