Motor protection units with phase reverser and rotation control are used as accessories for ground-mounted pumps with a three-phase motor. The motor protection unit protects the pump motor during operation, the phase reverser makes it possible to change the phase sequence so that the impeller runs in the correct direction, and the rotation control confirms that the direction of rotation is correct. The products are available in two voltage classes, 400 V 16 A and 400 V 32 A, and within each class there are several amperage ranges – from 1.0–1.6 A up to 20.0–25.0 A. The selection is made based on the pump motor's rated current so that the protection unit falls within the correct range. If you need help matching the right protection unit to the right pump and application, we are happy to offer advice.
