Here’s a short summary of the ABB AX, A, and AF series contactors — commonly used industrial contactors from ABB for motor and power control:

ABB AX Series Contactors

Purpose: General-purpose AC contactors for motors, heaters, lighting, and power circuits.

Design: Compact 3-pole design with optional auxiliary contacts.

Voltage & Ratings: Typically up to 690 V AC, with current ratings from small (e.g., AX09) up to larger sizes (e.g., AX65 and above).

Features: Reliable switching, space-efficient, easy to install. Meets IEC 60947-4-1 standards.

Example models:
• – mid-range AX series contactor.

ABB A Series Contactors

Description: Classic ABB contactor design for 3-phase motor control and power switching.

Design: Across-the-line contactor with double-break contacts for reliable switching.

Use Case: Suitable for many industrial motor control applications, usually with AC coils.

The “A” series is the traditional ABB contactor line, while newer ranges (like AF) build on and improve this platform.

ABB AF Series Contactors

Modern, advanced design: AF series is a new-generation contactor that improves on older A type designs with better performance and efficiency.

Wide control voltage range: A single AF coil often covers a broad range of AC & DC control voltages, reducing variant count.

Built-in surge suppression: Handles coil surges internally — no external suppressor needed.

Reliable in unstable networks: Designed to tolerate voltage sags and dips without malfunction.

Applications: Ideal for motor starters and general power switching up to high currents (wide range).

Example models:
• – Compact AF contactor for small/medium loads
• – Another AF series option
• – AF series for slightly larger load
• – Smaller AF model
