Рекомендации по выбору

✅ Select when motor rated current falls within 10～16A

⚠️ Optimally set operating current near the middle of adjustment range; avoid continuous operation at the lower limit of 10A

⚠️ For motors with frequent heavy-duty start-up, calculate starting current; upgrade to MS132 series if necessary

🔁 In-platform upgrade alternative: MS132-16 (более высокая отключающая способность, expanded accessory compatibility); domestic alternatives: Schneider GV2ME16, CHINT NS2-25 (10～16A)

Terminal Markings

Top terminals: 1Л1, 3Л2, 5Л3 (Power supply incoming)

Bottom terminals: 2Т1, 4Т2, 6Т3 (Motor load outgoing)

Typical Applications of АББ MS116-16 (3П, 10～16A)

Adjustable current range: 10～16A; suitable for 3-phase motors ≤7.5kW @400V. Combines overload, short-circuit and phase-loss protection in one unit, replacing separate circuit breaker + тепловое реле перегрузки. Designed for direct-on-line (DOL) motor circuits.

General Industrial Applications
Фанаты (3~7,5 кВт)

Workshop exhaust fans, dust extraction fans, centrifugal fans, oven circulating fans, вентиляторы градирни.

Operating feature: Light-load start, stable operation. Built-in phase-loss protection prevents motor burnout from single-phasing.

Насосы (3~7,5 кВт)

Circulating pumps, cooling water pumps, насосы для чистой воды, small sewage pumps, chilled water circulation pumps for HVAC systems.

Примечание: Submersible pumps require level control; confirm motor current is within 10～16A before selection.

Conveying Equipment

Light-duty belt conveyors, роликовые конвейеры, пластинчатые конвейеры, small elevators.

Suitable for light loads; NOT recommended for frequent forward/reverse impact loads. Upgrade to MS132 for heavy frequent start-stop duty.

Drives for Packaging Machinery

Small carton sealers, conveyor drive motors, stretch wrapping machines, small mixing motors.

ОВК & Building Services
Condenser fans of central air conditioning units, AHU supply/return fans
Underground car park ventilation fans, auxiliary smoke exhaust fans (excluding primary fire smoke exhaust fans; fire circuits require components complying with local fire codes)
Small circulation pumps for heat exchange stations
Plastics, Woodworking & Food Light Industry
Feeder motors & stirring motors for small extruders
Spindle motors for wood sanders and small cutting machines
Agitator pumps and conveyor motors for food production lines (dry environment)
Очистка воды & Охрана окружающей среды
Small chemical dosing agitator motors
Small aeration pumps, sludge screw conveyor motors
Drive motors for small filtration equipment

⚠️ Not Recommended Application Scenarios (Подводные камни выбора)

Motor rated current ＜10A or ＞16A (outside adjustment range)
Heavy-duty high-inrush equipment (air compressor main motors, large crushers) with extreme starting current
Motor circuits requiring star-delta starting or soft starters (MS116 only applies to direct-on-line starting)
High-impact loads and frequent stall conditions
Explosion hazardous areas (explosion-proof enclosure assembly required; unit itself has no Ex certification)
Projects where specifications mandate separate circuit breaker + тепловое реле перегрузки (integrated MMS cannot be adopted)

✅ Standard Control Configuration

MS116-16 + ABB Contactor → Direct-On-Line motor starter circuit

Дополнительные аксессуары:

HKF1-11 Auxiliary contact (running status feedback)

HKF1-02 Fault signalling contact (transmit overload/short-circuit trip signal to PLC)

Cross-Brand Equivalent Model List

Baseline specifications:

Adjustable current 10～16A｜3P｜Class 10A thermal-magnetic trip｜built-in phase-loss protection｜DIN rail mount｜integrated MPCB/MMS

⚠️ Important note: MS116 adopts rotary knob operation. Schneider GV2ME, Delixi CDP6 base versions use push-button operation. Mounting dimensions are compatible and electrical functions are equivalent, but operating style differs. Confirm operation type according to project requirements.

Critical Risks for Cross-Brand Replacement
Current Range Hard Limit

MS116-16 = 10～16A

❌ Forbidden substitutions: GV2ME16C (9～14A), 3RV2021-1AA10 (6～10A). Mismatched upper/lower limits lead to ineffective motor protection.

Operating Mechanism Difference

Поворотная ручка: MS116, GV3P, 3RV2021, PKZM0

Push-button: GV2ME, base CDP6, base NS2-25

Standardised cabinet projects & export machinery often require consistent operation form.

Instantaneous Short-Circuit Trip Threshold

ABB MS116 fixed instantaneous trip at 80A. Instantaneous thresholds vary between brands. Verify motor starting current for heavy-start loads to avoid nuisance tripping.

Accessory Incompatibility

Auxiliary contacts and fault signalling contacts from different brands cannot be interchanged. When retrofitting equipment, PLC feedback circuits need matching new accessories.
