Voltage Monitoring Type SW

Voltage Monitor for 3-Phase Networks

Undervoltage

Undervoltage monitor for three-

phase networks without N for

monitoring on voltage failure.

The voltage is being measured

between phases and an artiﬁcial

neutral point. At symmetrical

decreaseofthevoltagetoapprox.

50% of the nominal value or in

case of failure of a phase the

integrated relay (1 change-over

contact) releases with a delay of

approx.1s. Withenginesrunning-

SW31K

that the failure of a phase may be not detected. The

SW31K is available for measuring voltages AC 400 V

andAC690V.Assupplyvoltageinthestandardversion

AC 230 V is needed.

Application:

•

Monitoring of three-phase networks on loss of a

phase

monitoring of fuses

•
