Product overview
Original NOARK Ex9QR5 UL-listed solid-state reduced-voltage motor starters for three-phase AC200–690V. Select the current rating and specify the external bypass contactor, protective device and motor duty.
Technical selection summary
| Manufacturer / series | Original NOARK Ex9QR5 |
|---|---|
| Standards | UL 508 Listed, file E533416; UL 60947-4-2; CSA C22.2 No.14 / No.60947-4-2 |
| Motor circuit | Three-phase AC200–690V |
| Rated current | 15A, 22A, 30A, 37A, 44A, 60A, 74A, 90A, 110A, 150A, 180A, 220A, 264A, 320A, 370A, 440A, 500A, 560A, 630A, 710A, 800A, 900A, 1000A |
| Control supply | AC100–240V; 50/60Hz |
| Starting / stopping | Seven starting modes; soft stop/braking; programmable current limitation |
| Protection | Motor overload, phase-loss/unbalance, under/overvoltage and other documented protection functions |
| Bypass | No built-in bypass; external bypass contactor is required for the selected duty |
| Branch circuit | Use the manufacturer-specified coordinated MCCB or fuse; the soft starter is not the branch-circuit overcurrent protective device |
| Ambient / derating | -10°C to +40°C full performance; 40–50°C derate 2% per °C; altitude derating applies above 1000m |
This page covers the explicitly tabulated Ex9QR5-…-6-D non-bypassed models. Size the external bypass contactor and upstream short-circuit protective device from the manufacturer coordination tables; a current value alone does not establish motor horsepower for every voltage.
Typical applications
- Soft starting and stopping of pumps, fans, blowers and compressors.
- Motor applications requiring controlled starting current and coordinated overload/short-circuit protection.
