Protec Z LV

The universal solution for transient switching protection for LV motors, generators, transformer LV secundaries, VSD and UPS equipment

The filter is uniquely tuned to protect against these destructive spikes. More over the filter also has an integral clip device to ensure that the IEEE winding ageing limit is never exceeded. This is particularly important for motors, generators and transformer LV secundaries.

The filter is operative from -40 to +70degrees Celsius. It can withstand THD (V) up to 15%. The design is such that it can be directly mounted on the motors, generators and transformer secundaries without any provision for machine vibration effects. IP55 is allowed for to IEC specification publication 529

The flexible cable of 1500 mm can be shortened but not extended. These cables need to be connected to the incoming phases to the machine or device. The phase sequence does not have to be observed in order to connect this filter.

The filter earth stud needs to be connected to machine or device earth with a cable of less than 0.2 Ohm overall resistance and minimum a cross-section of 10 mm squared. It is imperative that the lightning earth and machine earth are connected and that the resistance between the two earths is less than 0.2 Ohm with a cross section of minimum 16 mm squared.
