Why Choose the ABB AF50-40-00 Contactor?
The ABB AF50-40-00 is a 4-pole DC-operated block contactor designed for reliable switching of industrial power circuits. Part of the ABB AF contactor range, this exact version combines four normally open main poles with an electronic coil interface rated for a 20–60 V DC control supply.
With its 4NO main contact configuration, the AF50-40-00 can simultaneously switch four conductors and is well suited to non-inductive or slightly inductive loads. The electronic coil interface provides dependable operation from low-voltage DC control systems used in industrial machinery, automation panels and power-control equipment.
ABB order code 1SBL357201R7200 identifies this exact 20–60 V DC AF50-40-00 variant. It provides an IEC AC-1 rated operational current of 100 A at up to 40 °C, a UL/CSA general-use rating of 80 A at 600 V AC and has no built-in auxiliary contacts.

Reliable Four-Pole Switching with Low-Voltage DC Control
The ABB AF50-40-00 uses four normally open main contacts to provide coordinated switching of multiple conductors from a single contactor. Applying the specified 20–60 V DC control voltage energises the electronic coil interface and actuates all four main poles, providing remote control of the connected power circuit.
The four-pole AF50 configuration is particularly suitable for industrial applications involving non-inductive or slightly inductive loads, including resistance heating and similar equipment. Its wide DC control range also supports integration into machinery and automation systems where low-voltage DC control power is standard.
Typical Applications
- Industrial four-pole power switching.
- Resistance heating and furnace control.
- Non-inductive and slightly inductive load switching.
- Industrial lighting control systems.
- Machine and automation control panels.
- Low-voltage DC-controlled OEM electrical equipment.
