SSU33L/AC400V 50HZ

The SSU33L 3-phase mains monitoring device is an easy-to-use monitoring relay for the 230V/400V 3-phase mains.
This device is available in two versions. One is the SSU33L/AC230V for a network with neutral conductor, and the other is the SSU33L/AC400V for a network without neutral conductor.
The devices monitor the conductor voltages, frequency, symmetry and direction of rotation. The monitoring criteria are linked internally and their sensitivity is set by the operator using a rotary knob.
A second rotary knob is used to set the alarm delay.
