Application Scenarios of シーメンス 3RV6011-1AA15

設定電流: 1.1-1.6あ, compatible with 0.55kW three-phase motor at 400V, Class 10 trip characteristic, built-in 1NO+1NC auxiliary contacts, S00 frame size (45 mm width). 過負荷を与える, short-circuit and phase-failure protection. Auxiliary contacts can be used for fault alarm and PLC signal feedback.

1. Typical Motor Load Applications
2. 小型ファン & cooling fan motors

Equipment cooling fans, cabinet ventilation fans, small HVAC fans. Continuous-run loads with moderate starting current. Offers phase-loss and overload protection; auxiliary contacts transmit fan fault signals.

2. Miniature water pumps & 循環ポンプ

Small process circulation pumps, cooling water pumps, laboratory pumps. Rapid thermal tripping upon pump stalling to prevent motor burnout.

3. Small conveying & drive equipment

Mini belt conveyors, small rollers, feeding mechanisms, compact conveyor drives. For standard direct-on-line (DOL) starting. Combined with 3RT7 contactors for complete motor starter assemblies.

4. Machine-tool auxiliary drive motors

Machine-tool coolant pumps, 潤滑ポンプ, small feed auxiliary motors. コンパクトなキャビネットの設置; fault signals sent to PLC for equipment alarm.

5. Small actuators for packaging & 印刷機械

0.55 kW three-phase drive motors for compact packaging machines, labellers and printing auxiliary equipment.

2. Non-motor & System-level Applications
3. Protection for small three-phase control transformers

Overload and short-circuit protection for low-inrush small-size transformers. Not suitable for transformers with high magnetizing inrush current.

注記: Use 3RV64 series for transformers with heavy inrush to avoid nuisance tripping.

2. Compact motor feeder circuits inside control cabinets

High-density DIN-rail layout for multi-loop small-motor cabinets. Built-in 1NO+1NC eliminates extra auxiliary contact modules; outputs trip/closed status signals to PLC and HMI.

3. Motor protection inside standalone machines

Integrated protection for built-in machine motors. Can also serve as an isolating switch for maintenance.

3. Industry Sectors

産業オートメーション: Custom special-purpose machinery, test equipment

空調設備: Unit internal small fans and circulation pumps

工作機械: Coolant and lubrication pump motors

マテリアルハンドリング: Mini conveying mechanisms

研究室 & test equipment: Small three-phase drive assemblies

Compact control cabinets & OEM export equipment (Domestic 3RV6, cross-compatible with imported 3RV2011-1AA15)

4. Recommended System Configurations
5. Direct-on-line (DOL) starter: 3RV6011-1AA15 + 3RT7 contactor. Complete motor protection-starter unit. 3RA1931 bus module enables fast assembly without inter-wiring, キャビネットのスペースを節約する.
6. Signal feedback configuration: NC contact for fault alarm; NO contact for closed-state feedback, connected to PLC digital input modules.
7. Non-applicable Conditions
8. Frequent heavy-duty starting and high-shock loads (incompatible with Class 10 trip characteristic)
9. Motors with rated current outside 1.1-1.6 A range
10. Transformers with high magnetizing inrush risk of unwanted tripping
11. Outdoor environments with heavy dust or corrosive atmosphere (requires additional protective enclosure)
