Controller A3RW 1.5/1/S/IP 21 17886-9980

Three-phase fan speed controller A3RW 1.5/1/S/IP 21

This speed controller, catalog number 17886-9980, is an autotransformer device designed for five-stage speed control of three-phase motors in ventilation and heating systems. Its solid construction and safety features make it a reliable element of professional installations.

Versatile application and safety

A3RW is not only the ability to precisely control the fan speed, but also a high level of safety. Equipped with a fuse, anti-freeze protection and thermal protection, it protects both the installation itself and the connected devices. The IP21 protection class provides resistance to dust and splashes, which is particularly important in harsh industrial conditions. The controller is operated using a knob, which ensures intuitive operation. Additionally, it has a backlight in the "ON" position, making it easier to work in low light conditions.

Technical specifications and mounting

The device is designed to operate in three-phase (3 phases) networks with a voltage of 3x400V and a frequency of 50/60Hz. It has five speed control levels, allowing you to adjust the fan performance to current needs. Its dimensions – width 215 mm, height 135 mm and depth 250 mm – allow for mounting in various installation configurations. A switching contact increases its functionality in more complex control systems.
