Product Q&A

Q:What is the difference between Type A and Type B Earth Leakage Relays?

Type A Earth Leakage Relays are designed for Alternating and Pulsating DC Currents. Type B Earth Leakage Relays are designed for AC, Pulsating DC, and Smooth DC Currents.

Q:How to choose compatible earth leakage CTs for the earth leakage relay?

First, you need to check the CT ratio of the earth leakage relay. Both the CT ratio of CTs and the earth leakage relay are similar. If your earth leakage relay's CT ratio is 2000:1, you need to choose CT ratio of the Current transformer is 2000:1.

Q:Can I request a customized earth leakage relay?

Absolutely! We offer oem & ODM service.

Q:How do I place an order?

Q:What is the warranty period for this relay?

Standard warranty is 12 months or 2,000 operating hours. Extended warranty up to 36 months is optional.
