The RectorSeal 96415 RSH-50 Surge Protective Device is a professional-grade surge protection solution designed specifically for single-phase 120/240V HVAC systems. Built to defend condensers, air handlers, heat pumps, and mini-split units from transient voltage surges, the RSH-50 helps prevent expensive electronic board failures and compressor damage.
This Type 1 SPD combines Gas Discharge Tube (GDT) technology with Thermally Fused Metal Oxide Varistor (TFMOV) protection, delivering fast response time and long-term reliability in real-world field conditions.
The compact design allows installation directly at the equipment disconnect or electrical panel without adding bulk. A built-in green LED indicator confirms active protection status, allowing technicians to quickly verify system safety during service calls.
If you are installing high-value HVAC equipment, surge protection at the disconnect is mandatory. The RSH-50 is simple, durable, and built for contractor installs.
