Description
The phase sequence monitoring
relay is enclosed in an S-95 slimline
housing. There are 3 versions
available.
Features:
● Relay output: 2 auxiliary contacts
(C/O)
● Rotary field direction monitor
● Detects defective fusing and
phase failure, provided there is no
voltage feedback via connected
motors
● LEDs for faults and supply
voltage.

sequence, contacts 11-12 and 21-24
are open, contacts 11-14 and 21-22
are closed. When the system is at
standstill (load isolated from
measurement inputs) the S1PN
can detect phase failure.

The phase sequence monitoring
relay detects the timed sequence of
individual phases in a three phase
supply. In a clockwise phase
sequence, contacts 11-12 and 21-22
are open, contacts 11-14 and 21-24
are closed. In an anticlockwise phase
