المميزات والفوائد
- Five-function protection in one device — phase failure, sequence, asymmetry, overvoltage, undervoltage — replaces five separate monitoring relays with a single 22.5 mm DIN-rail device, reducing panel space and wiring.
- Phase failure detection within 2–4 seconds of single-phasing provides a critical final protection layer before the thermal overload relay trips, preventing motor burnout in the most common supply-side failure mode.
- Phase reversal detection prevents damage from reversed motor rotation after maintenance reconnection or transformer replacement, catching connection errors before pumps run backwards.
- Direct three-phase supply connection — no CT or VT required — makes installation as simple as connecting supply wires and adjusting two threshold pots, achievable by any qualified electrician.
- Adjustable response time (2–20 seconds) prevents nuisance tripping during momentary supply disturbances such as motor starting voltage dips while still protecting against sustained phase failure.
- Asymmetry detection at >10% phase voltage imbalance identifies deteriorating supply conditions before imbalance causes excessive negative-sequence heating in motors.
- Single changeover output contact rated 5 A, 250 V AC directly interrupts the motor starter's control circuit or activates an alarm without additional interface relays.
التطبيقات الصناعية
- Three-phase motor protection in industrial motor starter panels across ARAMCO, SABIC, and NWC facilities, providing supply quality protection in addition to the thermal overload relay's load-current protection.
- Pump motor protection in water booster stations and irrigation pump panels, where phase failure detection prevents undetected single-phasing at unmanned remote pump stations.
- HVAC chiller and air handling unit motor protection in commercial buildings, where phase reversal detection catches reconnection errors after equipment maintenance.
- Industrial compressor motor protection at manufacturing facilities, where asymmetry detection identifies deteriorating supply quality before motor insulation damage accumulates.
- Generator output monitoring in standby power systems, where the 3UG verifies generator output voltage, phase sequence, and balance before the transfer switch connects the generator to the critical load bus.
- Supply quality monitoring at oil field pump station motor control panels in remote desert locations, where simple two-pot commissioning allows field technicians to set up monitoring without specialist equipment.
- Transformer secondary supply monitoring in industrial substation distribution boards, where asymmetry detection identifies unequal single-phase loading causing transformer neutral current and overheating.
