Suppressors

They protect against voltage spikes and transients coming from the public power grid or produced internally by the operation of high consumption equipment within our own power grid. They reduce by up to 80% the vulnerability to electrical problems ranging from erratic behavior to total destruction of the equipment or sensitive critical load.

The IEEE recommends using three levels of protection starting with suppressors in main boards, then in intermediate boards and finally in final boards. If this cascade protection is not available, the recommended suppressor should be increased by one level. Three-phase suppressors can be used in single-phase and two-phase boards.

All surge suppressors must be connected by means of a thermal switch, either to the load center or to the equipment to be protected, for service purposes.the capacity of the switch as well as the wire gauge used vary according to the suppressor.

The length of the wiring should not exceed 90cm. and the shorter the better, it is important to avoid curves or bends greater than 90°. This affects the response speed of the suppressor.
