ABB AF52-30-00-11 AF Contactor, 24 V ac/dc Coil, 3-Pole, 100 A, 22 kW, 3NO, 690 V ac

This contactor from ABB is designed to switch power to the electric circuits of a device on and off. A contact voltage rating of 690V AC and a current rating of 100A make it suitable for use in heavy-duty equipment. Thanks to its broad operating temperature range between -40°C and +70°C, this unit can withstand harsh environments. It comes with integrated surge protection, eliminating the need for an external surge suppressor and saving space in tight setups.

• Screw terminals for simple installation and stable electrical connections
• Power rating of 22kW for reliability in high-power operations

• Lighting fixtures
• Electric motors
• Consumer electronics
• Safety systems
• Transformers

When current passes through the integrated electromagnetic coil of the contactor, this creates a magnetic field that activates the contacts to move in a specific way based on their design. As this is a normally open contactor, the contacts will come together, closing and allowing the current to flow through the circuit. When the power is cut off, the contacts will re-open, causing the circuits to be de-energised.
