The cm-pvs.41s relay is within the CM three-phase monitoring range.
This relay operates at rated control power supply voltage,
three-phase measurement of 300-500 V AC voltage, and a rated 250
V/4 A cm-pvs.41s monitor phase parameter overvoltage/undervoltage,
phase loss fault with a 2 C/O output contact. The corresponding
threshold can be adjusted. Phase sequence monitoring, as well as
one or two trip delays, are optional. The adjustable range of trip
delay is instantaneous 30 seconds (0, sufficient). To prevent
unauthorized modifications, a sealable transparent cover can be
used as an attachment. This device provides screw connection
technology for dual cavity cage connection terminals.
