RectorSeal RSH-50 60A Non-Fused HVAC Disconnect with Built-In Surge Protection | NEMA 4X Weatherproof Disconnect Box

Professional HVAC Disconnect with Built-In Surge Protection

The RectorSeal RSH-50 60A Non-Fused HVAC Disconnect with Built-In Surge Protection combines safe electrical disconnect functionality with advanced surge protection in one contractor-grade solution. Designed for air conditioners, heat pumps, condensers, and ductless mini-split systems, this all-in-one disconnect box helps protect sensitive HVAC electronics from damaging voltage spikes, lightning strikes, and transient power surges.

Featuring a factory-installed RSH-50 Surge Protective Device, this pre-wired disconnect reduces installation time, minimizes parts inventory, and simplifies field wiring while helping maintain safe, code-compliant installations.

Two Devices. One Install. Half the Time.

Unlike traditional disconnect installations that require separate surge protection components, the RectorSeal RSH-50 PDB combines both products into one integrated unit. HVAC professionals benefit from faster installation, cleaner wiring, and improved long-term equipment protection.
