1. 3RT: 천랑성 Electromagnetic Contactor 시리즈
2. 1: Classic imported SIRIUS 3RT1 Series (국내 상당: 3RT5/3RT6)
3. 0: 3-pole contactor for motor loads (3주요 연락처 없음)
4. 64: Frame Size S10, AC-3 rated current 225 에이
5. 6: Conventional electromagnetic operating mechanism (non-electronic coil)
6. 에이: Coil voltage code → AC/DC 220～240 V (범용 AC/DC 코일)

전체 설명: 3-pole power contactor, Frame S10, busbar terminals, 220~240 V AC/DC coil, 결정된 2 평상시 열림 + 2 상시 폐쇄 보조 접점.

2. Main Electrical Specifications

Cable Connection Capacity

주회로: Stranded cable 70～240 mm²

보조 회로: 0.5～4 mm²

3. 개요 & Installation Information

장착 방법: Base plate screw mounting (DIN rail mounting NOT supported; large S10 frame can only be fixed to cabinet base plate)

Front protection class: IP00

주변 작동 온도: -25℃ ~ +60℃ (full-load operation at 60℃)

4. 일반적인 애플리케이션 시나리오

Direct-on-line starting of 3-phase induction motors, main contactor for star-delta starters, VFD 우회

공기 압축기, 물 펌프, 팬, 사출 성형 기계, high-power production line drives

공조, 발전소, 야금, port crane power circuits

⚠️ Not recommended for long-term inching operation under AC-4 duty; select higher frame size for frequent start-stop applications.

5. Alternative Selection Reference

1) Direct OEM replacement (Siemens original)

3RT1064-6AP36 (대상 모델, 220~240 V AC/DC coil)

Coil voltage variants:

3RT1064-6AP36 = 220~240 V AC/DC

3RT1064-6BP36 = 110~127 V AC/DC

2) 업그레이드된 대안

3RT1065-6AP36: Frame S10, AC-3 265 에이 (Higher capacity, 동일한 장착 치수)

⚠️ Important distinction: 3RT12xx series are vacuum contactors with different construction; not directly interchangeable.

Domestic economical model: 3RT5064 (AC-only coil, different terminal structure; cannot directly replace imported busbar-type 3RT1064).

6. Selection Pitfall Reminders
7. Main circuit adopts busbar connection, not cable terminals; terminal adapter accessories are required if cable wiring is needed.
8. S10 frame without DIN rail base, only base plate mounting available.
9. 범용 AC/DC 코일; compatible with both AC230 V control and DC220 V control circuits.
10. Auxiliary contacts 2NO+2NC are permanently built-in, cannot be removed or reconfigured freely.
11. Standard ordering designation with hyphen: 3RT1064-6AP36, do not omit the hyphen.
12. Optional Compatible Accessories

3RU thermal overload relays (S10 frame rating)

서지 억제기 (RC network, 코일 보호용 배리스터)

Mechanical interlock kits (for forward/reversing contactor pairs)

Main circuit terminal adapters (cable-to-busbar transition)

Mounting Dimensions – Siemens 3RT1064-6AP36 (Frame S10)

Important Precondition: DIN rail mounting is not supported; only base plate bolt mounting

1. Overall Outer Dimensions (폭 × 높이 × 깊이, mm)

폭W: 145 mm

Height H: 210 mm

Depth D: 202 mm (cabinet internal depth occupation)

2. Base Plate Mounting Hole Dimensions (Critical for cabinet sheet metal processing)

4 fixing through holes, bolt specification: M8

1. 수평 중심 거리 (left-right): 124 mm
2. 수직 중심 거리 (up-down): 186 mm
3. 장착 구멍 직경: Φ9 mm (for M8 bolts)

Bounding outline of mounting hole centers: 124 mm (여) × 186 mm (시간)

3. Wiring Clearance for Main Circuit Busbar

Main terminals exposed on top and bottom for busbar installation:

Phase spacing: 50 mm

Terminal bolt: M12

Recommended maximum busbar thickness ≤12 mm

4. Minimum Cabinet Installation Clearance (Siemens official heat dissipation specification)

Top clearance above contactor: ≥10 mm

Bottom clearance below contactor: ≥10 mm

Left & right side clearance: ≥10 mm

Front clearance (towards arc shield): ≥20 mm

Insufficient clearance causes temperature rise and derated operation.

5. 무게

Net weight of unit: 대략. 7.8 kg

6. Supplementary Installation Notes
7. 3RT1064-6AP36 = busbar connection version. Cable-terminated models of the same frame share identical overall dimensions, only terminal structure differs.
8. 3RT1065 (265 에이) of the same series uses S10 frame; mounting dimensions are fully interchangeable, base plate hole layout can be reused.
9. Minimum center-to-center distance between two side-by-side contactors with mechanical interlock for forward/reversing circuit: 150 mm.
10. For continuous full-load operation above 40℃ ambient temperature, expand surrounding heat dissipation clearance to minimum 15 mm.

Service Life Parameters – Siemens 3RT1064-6AP36 (Frame S10)

1. 기계적 수명 (Typical value from official datasheet)

기계적 내구성: 10,000,000 작동주기 (10 백만 번)

정의: No-load open/close cycles without main circuit load. Built-in standard mechanical auxiliary contacts (2아니요+2NC) do not reduce mechanical life.

⚠️ Distinction:

If electronic auxiliary modules are fitted → mechanical endurance reduced to 5,000,000 사이클.

Standard built-in 2NO+2NC mechanical auxiliary contacts of this model are not subject to this limitation.

2. 전기적 수명 (주요 연락처, key reference for selection)

Duty condition: AC-3, 400 다섯, normal motor start-stop (breaking 6×Ie starting current)

Electrical endurance ≈ 200,000 사이클 (200,000 타임스)

AC-4 inching duty (잠긴 로터, frequent reversing): Electrical life drops significantly, typically limited to tens of thousands of cycles. Select higher-rated contactor or dedicated AC-4 contactor for frequent jogging applications.

3. Key Supplementary Notes
4. Mechanical life ≠ Electrical life

Mechanical endurance reflects durability of magnetic core, springs and transmission mechanism; electrical endurance is limited by contact arc erosion. In most operating conditions, electrical service life expires first.

2. Environmental Influences

고온, 먼지, 습기, coil voltage deviation and vibration will shorten both mechanical and electrical service life.

3. Maximum Permissible Operating Frequency

표준근무: ≤1200 cycles/hour. Exceeding this frequency requires current derating, resulting in aggravated temperature rise and accelerated service life reduction.

4. Interchangeability within Frame

All S10 frame contactors including 3RT1064 / 3RT1065 share uniform mechanical endurance of 10 백만 사이클, applicable for reference.
