202
3-PHASE VOLT MONITOR Description The 202 series is a three-phase, auto-ranging, dual-range voltage monitor that protects 190–480 V ac, 50*/60 Hz motors regardless of size. The 202-RP (and the 202-575-RP for 475–600 V ac) monitors the phase rotation of the three-phase systems and trips on reverse-phase only. Critical applications include fan motors, scroll compressors,… Read more »

35040026
3-PHASE VOLT MON/ 38 Description The 350 series is a heavy-duty voltage monitor. This product should be used when high current relays or dual contacts are required, or 480 V controls are used. Since the 350 series uses heavy-duty relays, it comes in fixed voltage range models rather than a dual auto-ranging version like… Read more »

DLMUBRAAA
3-PH VOLTAGE MONITOR Description The DLMU Series is a universal voltage, 3-phase voltage monitor. It continuously measures the voltage of each of the three phases with micro-controller accuracy and compares the value to preset trip points. It separately senses phase reversal and loss; over, under and unbalanced voltages; and over or under frequency. Protection… Read more »
