Why Choose the ABB AF50-40-00 Contactor?
The ABB AF50-40-00 is a 4-pole block contactor designed for reliable switching of industrial power circuits. Part of the ABB AF contactor range, it combines four normally open main poles with electronic coil technology for dependable operation across a wide control-voltage range.
This AF50 configuration provides 4 normally open main contacts and no built-in auxiliary contacts, making it particularly suitable for applications requiring simultaneous four-pole switching. ABB AF four-pole contactors are primarily intended for controlling non-inductive or slightly inductive loads, including resistance heating and similar industrial loads.
ABB order code 1SBL357201R7000 identifies this exact AF50-40-00 configuration with a 100–250 V AC/DC electronic control circuit. The contactor provides an IEC AC-1 rated operational current of 100 A at up to 40 °C and a UL/CSA general-use rating of 80 A at 600 V AC.
Key Advantages
- Industrial 4-pole ABB AF50 block contactor.
- 4NO main contact configuration for simultaneous four-pole switching.
- Wide-range 100–250 V AC/DC electronic control circuit.
- 100 A AC-1 rated operational current at ambient temperatures up to 40 °C.
- 80 A UL/CSA general-use rating at 600 V AC.
- ABB AF electronic coil technology provides built-in surge suppression.
Key Features
- ABB AF50 contactor series.
- 4 normally open main poles.
- No built-in auxiliary contacts.
- 100–250 V AC at 50/60 Hz control range.
- 100–250 V DC control range.
- Electronic coil interface accommodates substantial control-voltage variation.
- Built-in surge protection reduces the need for an additional coil surge suppressor.
- Front- and side-mounted auxiliary contact blocks can be added where required.
Reliable Four-Pole Switching with Electronic Coil Control
The ABB AF50-40-00 uses four normally open main poles to provide coordinated switching of multiple conductors from a single contactor. Its electronic coil interface allows operation from either AC or DC control power across the specified 100–250 V range, simplifying integration into industrial control systems with different supply standards.
ABB AF four-pole contactors are designed primarily for non-inductive and slightly inductive loads such as resistance heating equipment. Integrated surge protection within the electronic coil interface also helps protect the control circuit from switching transients without requiring a separate external coil surge suppressor under normal installation conditions.
Typical Applications
- Industrial four-pole power switching.
- Resistance heating and furnace control.
- Non-inductive and slightly inductive load switching.
- Industrial lighting control.
- Machine and automation control panels.
- Power distribution and OEM electrical equipment.
