3-Phase Under & Over Voltage & Phase Monitor Relays, PM-017 / PM-017N Series
Brand :
PRIMUS
Caution
Product Description
• Relays for overload protection Phase sequence and phase loss for 3-phase 3-wire (PM-017) and 3-phase (4-wire) systems (PM- 017N)
• There is a split button that adjusts the voltage drop between 80 to 95% volts and the overvoltage between 105 and 120% volts.
• Check the Phase Sequence of the 3-phase power system. motor protection
• Check phase loss in one or more phases. One phase, even if there is back light from the motor (back e.m.f.) the motor is empty.
• LED display on relay operation.
• Suitable for 3 phase load protection corrupt because the voltage falls over. Phase sequence is invalid and phase is missing.
• In case of PM-017N (3 Phase 4 ), if the neutron is missing, the relay will not operate.
