1SFL527062R1222 ABB AF205B-30-22RT-12 48–130 V AC/DC Contactor

Why Choose the ABB AF205B-30-22RT-12 48–130 V Contactor?

The ABB AF205B-30-22RT-12 is a heavy-duty 3-pole contactor from the ABB AF Large range, engineered for demanding motor-control, isolation, bypass and power-distribution applications. Identified by ABB order code 1SFL527062R1222, this exact railway-oriented version combines ABB AF electronic coil technology with ring tongue terminals and pre-mounted auxiliary contacts.

The AF205B-30-22RT-12 features 3 normally open main contacts and 2 NO + 2 NC auxiliary contacts. Its electronically controlled coil operates across a wide 48–130 V AC 50/60 Hz and 48–130 V DC control range, while built-in surge suppression helps protect the associated control circuit from switching transients.

Designed for substantial loads, the AF205B platform provides an IEC AC-3 motor rating of 110 kW at 380–400 V AC and an AC-1 operational current of up to 350 A at 690 V and 40 °C. Its ring tongue connections, robust construction and railway-related approvals make it particularly suitable for applications exposed to vibration, voltage variation and demanding operating conditions.

Reliable Motor and Power Control for Demanding Applications

The ABB AF205B-30-22RT-12 is engineered for applications requiring high-capacity three-phase switching together with a robust control interface. Its wide 48–130 V AC/DC coil range allows the same contactor to operate across multiple nominal control voltages, while electronic coil control helps maintain reliable switching despite variations in the control supply.

Ring tongue connections and the AF205B railway-oriented construction make this model well suited to equipment exposed to shock and vibration. With pre-mounted auxiliary contacts, built-in surge suppression and substantial AC-3 and AC-1 ratings, it provides a comprehensive switching solution for rolling stock, motor starters, industrial machinery and power-control assemblies.

Typical Applications

• Railway and rolling-stock electrical systems.
• High-power three-phase motor starters.
• Motor starting and stopping circuits.
• Isolation and bypass systems.
• Industrial power distribution assemblies.
• Pumps, compressors, fans and conveyors.
• Heavy industrial machinery and automation systems.
