The Mersen® 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.
