4. 선택 지침

✅ 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 (더 높은 차단 용량, expanded accessory compatibility); domestic alternatives: Schneider GV2ME16, CHINT NS2-25 (10～16A)

5. Terminal Markings

Top terminals: 1L1, 3L2, 5L3 (Power supply incoming)

Bottom terminals: 2T1, 4T2, 6T3 (Motor load outgoing)

Typical Applications of 씨줄 MS116-16 (3피, 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 + 열 과부하 릴레이. Designed for direct-on-line (DOL) motor circuits.

1. General Industrial Applications
2. 팬 (3～7.5kW)

Workshop exhaust fans, dust extraction fans, centrifugal fans, oven circulating fans, 냉각탑 팬.

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

2. 슬리퍼 (3～7.5kW)

Circulating pumps, cooling water pumps, clean water pumps, small sewage pumps, chilled water circulation pumps for HVAC systems.

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

3. 운반 장비

Light-duty belt conveyors, 롤러 컨베이어, slat conveyors, 작은 엘리베이터.

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

4. Drives for Packaging Machinery

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

2. 공조 & Building Services
3. Condenser fans of central air conditioning units, AHU supply/return fans
4. Underground car park ventilation fans, auxiliary smoke exhaust fans (excluding primary fire smoke exhaust fans; fire circuits require components complying with local fire codes)
5. Small circulation pumps for heat exchange stations
6. 플라스틱, 목공 & Food Light Industry
7. Feeder motors & stirring motors for small extruders
8. Spindle motors for wood sanders and small cutting machines
9. Agitator pumps and conveyor motors for food production lines (건조한 환경)
10. 수처리 & 환경 보호
11. Small chemical dosing agitator motors
12. Small aeration pumps, sludge screw conveyor motors
13. Drive motors for small filtration equipment

⚠️ Not Recommended Application Scenarios (선택의 함정)

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

✅ Standard Control Configuration

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

옵션 액세서리:

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

ABB MS116-16 (3P｜10～16A, rotary knob type Motor Protection Circuit Breaker)

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.

1. Imported Brand Direct Equivalents

2. 국내 대안 (Cost-Effective Solutions)

3. Critical Risks for Cross-Brand Replacement
4. 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.

2. Operating Mechanism Difference

회전식 손잡이: MS116, GV3P, 3RV2021, PKZM0

푸시 버튼: GV2ME, base CDP6, base NS2-25

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

3. 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.

4. Accessory Incompatibility

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

4. Shortlist for Direct Procurement

✅ Perfect imported rotary-knob equivalents: Siemens 3RV2021-4AA10 / EATON PKZM0-16 / Schneider GV3P16

✅ ABB factory upgrade option: MS132-16

✅ Cost-effective domestic rotary-knob models: CHINT NS2-25X-16 / Delixi CDV2s-32 (10~16A)
