The relay is especially designed to be integrated easily into 3-ph terminal blocks. The relay can be fitted with a shunt or alternatively any other measurement system could be integrated.
Using the H-armature principle the polarised latching relays are noted for their high resistance to shocks and vibrations. They are always in a defined switching position and therefore there is no loss of information in case of power failure.
The relays are designed and manufactured in accordance to international standards of IEC 61810 part 1 as well as they meet the short circuit requirements for Supply Control Switches as of IEC 62052 part 31.
