The ZORC® is a unique high frequency transient over-voltage surge suppressor for the protection of motors, transformers and generators from spikes, surges and circuit switching.

Every year huge losses are incurred by end-users because of insulation failures of medium voltage (3KV – 40KV) motors, generators and transformers.

ZORC surge suppressor eliminates multiple pre-striking and re-striking (re-ignition) transients associated with vacuum and other switchgear. Suitable for both switchgear panel and machine terminal box mounting, the ZORC surge suppressor is an easy-to-apply, compact and low cost solution to the extremely expensive problem of motor, transformer and generator damage.
