Product Features & Fitment

This heavy-duty metal control housing encloses premium electrical contactors and multi-speed relays engineered to handle the inductive start-up loads of high-capacity RV compressors. By cleanly translating low-voltage 12V DC signals from the wall into line-voltage 115V AC operational power, it ensures safe, efficient cycling of the primary cooling assets without risking dashboard grid drops. It comes pre-wired with an integrated quick-connect wiring harness that plugs directly into the rooftop unit's junction port, eliminating raw-wire splicing inside the ceiling plenum.
