3-Phase Under & Over Voltage & Phase Breaking Relays, PM-019 / PM-019N Series

Caution
Product Description
• Relays for under/over voltage protection for each of phases
• Over/under voltage can be set using the adjustable knob.
• There is a button to separate the voltage drop between 80 to 95% and the overvoltage between 105 and 120%
• Protect phase loss in one phase or more than one phase. Even if there is back light from the motor (back e.m.f.) while the motor is empty.
• LED display of relay status
• In case model PM-019N (3-phase, 4-wire) if the neutron is missing, relay will not work.
