4. 選定ガイドライン

✅ 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 (より高い遮断容量, expanded accessory compatibility); domestic alternatives: Schneider GV2ME16, CHINT NS2-25 (10～16A)

5. 端子マーク

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

下部端子: 2T1, 4T2, 6T3 (Motor load outgoing)

Typical Applications of ABB MS116-16 (3P, 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 + サーマル過負荷リレー. Designed for direct-on-line (DOL) motor circuits.

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

Workshop exhaust fans, dust extraction fans, centrifugal fans, oven circulating fans, 冷却塔ファン.

Operating feature: Light-load start, 安定した動作. Built-in phase-loss protection prevents motor burnout from single-phasing.

2. パンプス (3～7.5kW)

Circulating pumps, cooling water pumps, 浄水ポンプ, small sewage pumps, chilled water circulation pumps for HVAC systems.

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

3. Conveying Equipment

Light-duty belt conveyors, roller conveyors, slat conveyors, 小型エレベーター.

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. 空調設備 & 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. Plastics, 木工 & 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 (乾燥した環境)
10. 水処理 & 環境保護
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 (Selection Pitfalls)

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 + サーマル過負荷リレー (integrated MMS cannot be adopted)

✅ Standard Control Configuration

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

オプションのアクセサリ:

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. 国内代替品 (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

ロータリノブ: MS116, GV3P, 3RV2021, PKZM0

Push-button: 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)
