Relay for phases rotation control - 2 CO contacts.

Pluggable on the following sockets : 9244, 9246, 9243 & 9946.

Detailed table of the coil resistance data is available in the technical support pages of this site or can be sent upon request.



Operation principle

In some installations, it is necessary to control automatically the way the phases follow one another.

The 3 phases are connected to a network made of resistances and capacitors.

A TEC relay of 1200 series is supplied by the vectorial sum of the voltages existing on the terminals of the two phase modifier network.

When the 3 phases follow the "1-2-3" way, the voltage is at maximum level and the relay is energized. In other cases, components are opposed and the relay is not energized.

In case a phase is lacking, the relay is not energized only if the wire is disconnected from the network and the load.
