Questions & Answers

Is this a genuine original part?

This is a premium quality aftermarket replacement part, manufactured to meet or exceed original equipment standards for fitment and performance in marine environments.

How do I know if it is compatible?

We recommend checking your current mounting space. This unit uses a standard 69mm x 69mm square base. If your system draws more than 100A continuous, we recommend our 300A heavy-duty model.

Can this be mounted through a panel?

Yes, this switch is designed for versatile mounting. It can be surface mounted or panel mounted by drilling a standard round hole and securing the square faceplate to the surface.

Note: Distributed by 4boats.co.uk. Please verify your original mounting dimensions and current requirements before purchasing.
