Surge Protection Devices (SPD)

  • Protect HVAC equipment from electrical surges, brownouts, and other voltage disturbances
  • Protection from up to 60,000-amp single surges and up to 20,000-amp repetitive surges
  • Surge protection solutions for ducted/ductless A/C, heat pumps, heating systems, and whole house.

Why RectorSeal RSH Series SPD's?

Integrated components, such as thermally fused MOVs and Gas Discharge Tubes (GDT), provide robust and compact protection. The circuit allows for 15 "hits" at nominal discharge current without failure and 1 "hit" at maximum surge current.

RSH-120 offers whole home protection with dual diagnostic LEDs and audible alarm.

UL 1449 listed, with thermally fused MOVs directly to the unit, providing the NEC's highest short circuit current rating (SCCR) to ensure the safety of every install.

RSH-VRM60A provides advanced voltage monitoring by letting the user define the appropriate voltage input range.

Each surge protection device comes with an unsurpassed industry product warranty; and an extended connected equipment warranty, typically multiple years long the competitive products.
