Perfect OEM fit – Direct replacement for dual positive cut off switch, designed to match the electrical specifications of the 2018 Freightliner Cascadia. No drilling or wiring modifications required; plug-and-play installation saves maintenance time.
Bipolar safety design – Dual Positive Cut Off Switch simultaneously disconnects the power from both positive battery terminals, eliminating parasitic power consumption and arc flash risks during vehicle maintenance, effectively preventing short circuits and electric shock hazards.
Reliability and durability - 500A continuous current capacity, using stainless steel hardware and tin-plated copper contacts, with excellent conductivity and corrosion resistance. The sealed housing is rainproof, oil-resistant and protects against road debris, ensuring reliable performance under extreme temperature and vibration conditions.
Efficient operation - One-click synchronisation to cut off both positive poles, no need to disconnect wires individually, allowing quick power cut during maintenance, towing, or long-term parking, improving operational efficiency.
Battery Life Extension & Cost Savings – Fully isolates the dual-battery system when the truck is parked for long periods, avoiding battery depletion and overcharging issues. Reduces battery replacement frequency by 25%-30%, cutting your fleet operation costs significantly.
