The Select2 product line combines selenium cells with the Current Technology patented Failure-Free Integrated Suppression Bus (ISB) to deliver the industry's best surge suppression performance. The ISB contains metal oxide varistors (MOVs), polypropylene capacitors and individual fuse protection, integrated with copper buss bar inside.
The Select2 is dual listed as both a Type1 and Type2 surge suppressor. This means the device can be installed upstream of the main service entrance to provide protection for sophisticated service entrance switchgear and circuit breakers.
