ProTec CM(R)

Overvoltage waves are slowly increasing at greater frequency, reoccurring and threatening devices. Incidence of low value surges are still too high for electronic elements and are common in the object itself, often caused by activation switching of major appliances, inductive devices and motors, or industrial system operation failures. SPDs in this classification are intended to protect sensitive electronic installations in Zones 1-2 per IEC 62305.

The ProTec CM modular series consist of high performance varistors for each pole and an optional high energy encapsulated gas discharge tube (GDT), separate thermal disconnect mechanisms. The plug-in module and base design facilitates replacement of a failed module without the need to remove system wiring.
