The Mersen®, distributed by Uni-Line®, Surge-Trap® Series Surge Protection Devices (SPD) safeguards residential air conditioning (A/C) units including mini-splits, furnaces, and air handlers from costly voltage surge events, such as fluctuations in power often generated from inside a home or building, and from an outside source like lightening. Compact in size, the Surge-Trap Series provides Type 1 and Type 2 surge protection to help maintain safe, reliable A/C and furnace performance. Model STXH240S05 safeguards residential A/C and furnace equipment, and models STXR480Y05 and STXR480Y05A are used for Commercial and Industrial applications and are recommended for replacement of obsolete surge arrestors. The STXR models are flexible in both line or load installation applications for branch panel or individual equipment protection.
