VOLTAGE RELAY 3-PHASES 230/400V TYPE: PNM-31
Product Description
The PNM-31 voltage relay is designed for three-phase system voltage control in order to protect load against voltage increase / decrease outside the preset range. There is a fixed OFF-time delay (approximately 5 seconds) set in the system. The device is capable of detecting incorrect phase sequence and voltage unbalance.
PRODUCT FUNCTIONAL FEATURES:
- Three-phase load protection against voltage swing and unbalance, and incorrect phase sequence,
- Control and indication of correct phase sequence and voltage unbalance,
- Relay state indicator,
- Control and indication of every phase voltage,
- Fixed OFF-time delay,
- Mounted on TH 35 rail.
- Minimum (170 ÷ 225 V) and maximum (235 ÷ 290 V) voltage adjustment,
- Relay output - changeover contact, maximum load 16 A,
