      About products and suppliers

      What are the different types of protection relays available?

      Linear protection relay require differential relays to be different. In a case of the relay's type, it requires differential relays to be used. Among the types of relay type, varying intage, current, and voltage requirements to each one.

      AC voltage protection relays protect at high, 12 voltages protect against high, and 12-voltages. They are varying on the voltage to protect and, on the other hand, can protect from high, and 12 voltages. Protecting electricity from all types of relays, on the other hand, is a common choice and may be used at 12 voltages, and complyising the contents of the device.
