الدائرة الرئيسية: Stranded cable 70～240 mm²

الدائرة المساعدة: 0.5～4 mm²

3. الخطوط العريضة & Installation Information

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

4. سيناريوهات التطبيق النموذجية

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

ضواغط الهواء, مضخات المياه, المشجعين, آلات صب الحقن, high-power production line drives

التدفئة والتهوية وتكييف الهواء, محطة توليد الكهرباء, علم المعادن, 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 (Subject model, 220~240 V AC/DC coil)

Coil voltage variants:

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

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

2) Upgraded alternative

3RT1065-6AP36: Frame S10, ايه سي-3 265 أ (Higher capacity, identical mounting dimensions)

⚠️ 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. Universal AC/DC coil; 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)

مثبطات الطفرة (RC network, varistor for coil protection)

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 (العرض × الارتفاع × العمق, مم)

Width W: 145 مم

Height H: 210 مم

Depth D: 202 مم (cabinet internal depth occupation)

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

4 fixing through holes, bolt specification: م8

1. المسافة المركزية الأفقية (left-right): 124 مم
2. المسافة المركزية العمودية (up-down): 186 مم
3. قطر فتحة التركيب: Φ9 mm (for M8 bolts)

Bounding outline of mounting hole centers: 124 مم (دبليو) × 186 مم (ح)

3. Wiring Clearance for Main Circuit Busbar

Main terminals exposed on top and bottom for busbar installation:

Phase spacing: 50 مم

Terminal bolt: م12

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. وزن

Net weight of unit: تقريبا. 7.8 كجم

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 أ) 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 مم.
10. For continuous full-load operation above 40℃ ambient temperature, expand surrounding heat dissipation clearance to minimum 15 مم.

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

1. عمر الخدمة الميكانيكية (Typical value from official datasheet)

التحمل الميكانيكي: 10,000,000 دورات التشغيل (10 مليون مرة)

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

⚠️ Distinction:

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

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

2. عمر الخدمة الكهربائية (جهات الاتصال الرئيسية, key reference for selection)

Duty condition: ايه سي-3, 400 V, normal motor start-stop (breaking 6×Ie starting current)

Electrical endurance ≈ 200,000 دورات (200,000 مرات)

AC-4 inching duty (الدوار مقفل, 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

ارتفاع درجة الحرارة, تراب, رطوبة, coil voltage deviation and vibration will shorten both mechanical and electrical service life.

3. Maximum Permissible Operating Frequency

Standard duty: ≤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 مليون دورة, applicable for reference.
