Why Choose the ABB AF95B-30-11RT Contactor?
The ABB AF95B-30-11RT is a robust 3-pole AF contactor designed for railway and demanding industrial motor-control applications. Part of the ABB AF Large / AF95B railway contactor range, it combines ABB electronic coil technology with ring-tongue terminals and a compact construction engineered for reliable power switching.
The AF95B-30-11RT provides 3 normally open main contacts together with 1 normally open and 1 normally closed auxiliary contact. It is suitable for three-phase motor switching and other industrial power-control duties, while the integrated auxiliary contacts support signalling, electrical interlocking and control logic.
This exact configuration, ABB order code 1SFL437062R7211, uses a wide-range 20–60 V DC control circuit. Its railway-oriented construction and ring-tongue terminal connections make it particularly suitable for rolling stock and other installations where secure electrical connections and resistance to demanding operating conditions are required.

Reliable Motor Control for Railway and Industrial Systems
Contactors provide electrically controlled switching for motors and other power loads, enabling equipment to be operated through automated control circuits rather than by directly switching the main power conductors. The ABB AF95B-30-11RT uses three normally open main contacts for three-phase load switching, while its normally open and normally closed auxiliary contacts support signalling, interlocking and sequencing functions.
The AF95B railway design is intended for demanding transportation environments and combines a wide-range electronic control circuit with secure ring-tongue connections. This makes the AF95B-30-11RT particularly suitable for rolling stock auxiliary systems, motor control assemblies and industrial equipment requiring reliable switching under vibration and other demanding operating conditions.
Typical Applications
- Railway rolling stock electrical systems.
- Three-phase motor starters and motor-control circuits.
- Train auxiliary equipment and machinery.
- Industrial conveyors, pumps and fans.
- Electrical interlocking and automation systems.
- Industrial power switching in demanding environments.
