These products are approved as UL Type 4- recognized components and are usable in Type 2 applications. The product range utilizes fast-acting metal oxide varistors to limit overvoltage to values compatible with network equipment. Product features include:
- Pluggable cartridges: When one or more cartridges reaches end-of-life, the electrical circuit need not be isolated, nor does the entire device need to be removed. Simply pull the dead cartridge from its housing and plug in a new one.
- Integrated auxiliary contact: optional remote monitoring capability. Wiring an integrated 3-point 1A volt-free contact enables the operational state of the SPD to be monitored remotely.
