Defend sensitive microprocessors in your HVAC, refrigerator, smart home automation, and electric vehicle from transient voltage spikes and lightning storms.
Today's modern home is filled with sophisticated microelectronics. It is not just your computers and televisions that contain sensitive circuit boards—your inverter-driven heat pump HVAC, smart refrigerator, induction range, washing machine, and electric vehicle charging station all rely on delicate microprocessors.
Standard plug-in surge strips only protect the single device plugged directly into them, and they offer zero protection for major hardwired appliances. Furthermore, over 80% of transient electrical surges originate from inside the home—generated whenever large inductive loads (like your air conditioner compressor or vacuum motor) cycle on and off.
Under NEC Article 242 (Overvoltage Protection), all newly installed or upgraded residential service panels are now legally mandated to feature a Type 1 or Type 2 Surge Protective Device (SPD). A panel-mounted Type 2 SPD intercepts voltage spikes at the service entrance, shunting excess voltage safely to ground before it can travel through your home's branch wiring.
