About this product

Master DC power disconnect switch kit available in 100A Key Switch or 275A Rotary Switch options.

Isolates your 12V DC power circuits safely by creating a physical air-gap disconnect between the battery bank and leisure circuits. This mechanical switch protects your electrical installation from accidental short circuits during maintenance, emergency cut-offs, or winter storage. Available in a removable-key 100A version or heavy-duty 275A continuous rotary model to suit your system demand. If you need rapid manual circuit isolation to safeguard your equipment and wiring, this kit is the ideal choice.
