The DSP Series surge arresters are a robust Class 2 arrester (8/20µs) available in single and three phase configurations.

The surge protection units feature a two stage arrester that gives your system double the protection of normal ‘plug in’ surge arresters. This allows identification of the possible lack of protection to be caught early and preparations made for the replacement unit to be installed (while the system is still protected).

Ideally suited to industrial and commercial projects such as hospitals, schools etc.

The CPN Distribution Surge Protection Series provides an economic means of preventing damage to electrical distribution systems from mainsborne transient voltages. These transients may occur as the result of a nearby lightning strike or surges derived from the switching of inductive or capacitive loads.

The CPN-DSP Series requires no maintenance but the LED’s should be checked at regular intervals to ensure that full protection is operational.
