ABB Contactor Standard Selection Procedure

(Industrial & 建物, for sales / quotation / design)

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

1. Define Application & Product Family

建物 / Residential / Distribution board: Lighting, 加熱, パンプス, ファン, small motors → ESB/EN series (silent, DINレール, narrow width)

Industrial / 装置 / Control cabinet: ファン, パンプス, コンプレッサー, motor main circuits → AF/A series (wide voltage, 長寿命, 頑丈な)

2. Determine Load Category (Critical for Derating)

Per IEC 60947 utilization categories:

AC-1: 抵抗負荷 (heaters, 点灯) → use rated current directly

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

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

3. Calculate Operating Current & 定格容量
4. Determine current from power / 電圧
5. Allow 1.1–1.25x safety margin (inrush, continuous duty)
6. Select corresponding rated current (つまり) from ABB catalog

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

4. Select Number of Poles

1P: 単相, single circuit

2P: 単相, double-pole (L+N switching, building standard)

3P: Three-phase motors / 工業用 (最も一般的な)

4P: 三相 + N or double-break

5. Select Coil Voltage & タイプ
6. Control voltage: 24V, 110V, 230V, 400V, 等.
7. Coil type:

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

Industrial: Wide-range coil (AF series, stable at 85–110% Un)

6. Define Auxiliary Contact Requirements

内蔵: From model (20=2NO, 02=2NC)

Expandable: EH series auxiliary contacts (1NO+1NC, 2いいえ, 等)

Used for: Status feedback, interlocking, sequential control

7. Environmental & 特別な要件

高度 >1000メートル, 温度 >40°C → derate or upsize

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

保護: IP20 normally sufficient for panel mounting

Mechanical interlock / 逆転する: Use dedicated interlock accessories

8. Final Verification: モデル + 認証
9. Confirm full model: family–current–contacts–coil

例: ESB20-20N-06

2. Verify certifications: CCC, IEC, RoHS
3. Confirm mounting: 35mm DINレール / ネジ取付

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
