Нагрузка двигателя (AC-7a/7b): Recommended ≤9A (4.6кВт) at 230V single-phase

Inductive load: Derating or surge suppressor recommended

2. Coil voltage selection:

Match control system supply (230В переменного/постоянного тока)

Other voltages available: ЭСБ20-20Н-01 (24В), ЭСБ20-20Н-04 (110В)

3. Конфигурация контактов:

Эта модель: 2НЕТ, suitable for two independent circuits

For NC contacts: ESB20-02N series (2Северная Каролина)

For auxiliary contacts: Add auxiliary contact modules

4. Условия окружающей среды:

Derate above +40°C ambient temperature

Extra protection required in humid or corrosive environments

5. Примечания по установке

Pre-Installation

Verify model matches order, inspect for physical damage

Confirm coil voltage matches control supply

Prepare standard 35mm DIN rail and suitable terminals

Процедура установки

Clip contactor firmly onto 35mm DIN rail

Wire main and control circuits per diagram; coil is non-polarized

Терминальный крутящий момент: 2.5Н·м (дирижер: 0.5–2.5mm²)

Accessories clip directly onto top/side without tools

Безопасность

Isolate and verify voltage-free before installation

Separate main and control wiring to avoid interference

Ensure adequate ventilation to prevent overheating

Maintain ≥5mm clearance around contactor for heat dissipation

ввод в эксплуатацию & Обслуживание

Check wiring before first energization

Test contactor operation for correct switching and no abnormal noise

Inspect contacts and terminal tightness regularly (at least annually)

ABB Contactor Standard Selection Procedure

(Промышленный & Здание, for sales / quotation / дизайн)

Using ESB (здание) and AF/A (промышленный) as examples – 8-step precise selection ready for proposals and quotations.

1. Define Application & Product Family

Здание / Жилой / Distribution board: Освещение, обогрев, насосы, фанаты, small motors → ESB/EN series (silent, DIN-рейка, narrow width)

Промышленный / Оборудование / Control cabinet: Фанаты, насосы, компрессоры, motor main circuits → AF/A series (широкое напряжение, долгая жизнь, heavy-duty)

2. Determine Load Category (Critical for Derating)

Per IEC 60947 utilization categories:

АС-1: Резистивные нагрузки (обогреватели, освещение) → use rated current directly

АС-3: Squirrel-cage motor DOL (most common industrial) → motor current ≤ contactor rated current

AC-7a/7b: Building small motors, фанаты, pumps → use building contactor rated values

3. Calculate Operating Current & Номинальная мощность
4. Determine current from power / Напряжение
5. Allow 1.1–1.25x safety margin (inrush, непрерывная служба)
6. Select corresponding rated current (Т.е.) from ABB catalog

Пример: 230V single-phase 2kW heater ≈ 8.7A → ESB20-20N is sufficient

4. Select Number of Poles

1П: Однофазный, single circuit

2П: Однофазный, double-pole (L+N switching, building standard)

3П: Трехфазные двигатели / промышленный (наиболее распространенный)

4П: Трехфазный + N or double-break

5. Select Coil Voltage & Тип
6. Управляющее напряжение: 24В, 110В, 230В, 400В, и т. д..
7. Тип катушки:

Здание: AC/DC universal coil (ESB series, non-polar, silent)

Промышленный: Широкодиапазонная катушка (серия АФ, stable at 85–110% Un)

6. Define Auxiliary Contact Requirements

Встроенный: From model (20=2НО, 02=2НЗ)

Расширяемый: EH series auxiliary contacts (1НО+1НЗ, 2НЕТ, и т. д.)

Used for: Status feedback, переплетение, sequential control

7. Относящийся к окружающей среде & Особые требования

Высота >1000м, температура >40°C → derate or upsize

Silent requirement (residential/office): Must use ESB silent type

Защита: IP20 normally sufficient for panel mounting

Механическая блокировка / реверсивный: Use dedicated interlock accessories

8. Final Verification: Модель + Сертификаты
9. Confirm full model: family–current–contacts–coil

Пример: ЭСБ20-20Н-06

2. Verify certifications: CCC, МЭК, РоХС
3. Confirm mounting: 35мм DIN-рейка / винтовое крепление

Simplified Selection Mnemonic

1. Choose family by application
2. Choose duty by load type
3. Calculate current with margin
4. Confirm poles and coil voltage
5. Add aux contacts for control
6. Check environment and derate
7. Verify model for final list
