ABB 1SBL417201R7200 4-Pole Contactor

Description

• The ABB 1SBL417201R7200 AF75 4-pole contactors are crucial components for controlling electrical loads, with a primary focus on non-inductive or slightly inductive loads such as resistance furnaces. These contactors are well-suited for managing power circuits with a maximum voltage rating of up to 690 V AC and 440 V DC. Additionally, they find applications in various scenarios, including lighting control.

• The standout features of the AF series contactors is their electronic coil interface, designed to accept a broad control voltage range. This interface seamlessly accommodates both AC (50/60 Hz) and DC power supplies, ensuring adaptability to different supply voltages and local electrical conditions. It enables the same contactor to be used across various countries and handle fluctuations in the control voltage due to local supply or network variations.

• The AF contactors are also known for their reliability in AC or DC control circuits that may be exposed to voltage interruptions or voltage dips. They offer several advantages, including a wide voltage range (e.g., 100 to 250 V AC and DC), the ability to manage significant voltage variations, reduced power consumption, noise-free operation, and the capability to withstand voltage interruptions or voltage dips in the control supply (as low as 20 ms).
