Current and Voltage Controls
3-Phase Voltage Sequence Control
Type SM 170
• 3-phase monitoring relay for phase
sequence/phase loss
• Measures when all 3 phases are present and
have the correct phase sequence
• Output: 10 A SPDT relay
• Plug-in type module
• S-housing
• LED-indication for power supply and output ON
• Power supply is the 3-phased measuring voltage
Product Description
Ordering Key
3-phase plug-in monitoring
and phase sequence/phase-
loss relay. Frequently used to
prevent a 3-phase motor from
running on only 2 phases or
to secure the right phase se-
quence when connecting a
load to the mains.
