2. Main Electrical Specifications

Cable Connection Capacity

Главная цепь: Stranded cable 70～240 mm²

Вспомогательная цепь: 0.5～4 mm²

3. Контур & Installation Information

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

Front protection class: IP00

4. Типичные сценарии применения

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

Воздушные компрессоры, водяные насосы, фанаты, машины для литья под давлением, high-power production line drives

ОВК, электростанция, металлургия, 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, АС-3 265 А (Higher capacity, одинаковые монтажные размеры)

⚠️ 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)

Surge suppressors (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 (Ш × В × Г, мм)

Width W: 145 мм

Height H: 210 мм

Depth D: 202 мм (cabinet internal depth occupation)

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

4 fixing through holes, bolt specification: М8

1. Горизонтальное межосевое расстояние (left-right): 124 мм
2. Вертикальное межосевое расстояние (up-down): 186 мм
3. Диаметр монтажного отверстия: Φ9 mm (for M8 bolts)

Bounding outline of mounting hole centers: 124 мм (Вт) × 186 мм (ЧАС)

3. Wiring Clearance for Main Circuit Busbar

Main terminals exposed on top and bottom for busbar installation:

Phase spacing: 50 мм

Terminal bolt: М12

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. Масса

Net weight of unit: приблизительно. 7.8 кг

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

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

1. Механический срок службы (Typical value from official datasheet)

Механическая выносливость: 10,000,000 рабочие циклы (10 миллион раз)

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

⚠️ Distinction:

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

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

2. Электрический срок службы (Основные контакты, key reference for selection)

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

Electrical endurance ≈ 200,000 циклы (200,000 раз)

AC-4 inching duty (заблокированный ротор, 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

Высокая температура, пыль, влажность, coil voltage deviation and vibration will shorten both mechanical and electrical service life.

3. Maximum Permissible Operating Frequency

Стандартная пошлина: ≤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 миллион циклов, applicable for reference.
