Key Features

• High-Current DC Switching – Outfitted with solid internal copper contacts optimized to sustain a 250A continuous load safely with minimal electrical resistance.

• Molded Arc Barrier – Features a prominent, integrated vertical plastic partition between the main female threaded copper terminals to eliminate the risk of external electrical arcing or flashover.

• Hermetically Sealed Design – The internal contact chamber is completely sealed to rapidly quench electrical arcs when breaking live high-voltage DC circuits, enhancing component longevity and safety.

• Reinforced Mounting Flanges – The dual corner mounting holes feature integrated metal crush sleeves, allowing the contactor to be securely torqued down to a chassis or battery enclosure without stressing the plastic housing under heavy vibration.

Ideal For:

• Main circuit isolation and pre-charge paths in light-to-medium electric vehicles (EVs)

• High-performance custom EV conversions and battery pack builds

• Grid-tied solar photovoltaic (PV) inverters and residential Battery Energy Storage Systems (BESS)

• Industrial DC power distribution and heavy-duty automated machinery control lines
