The BG Electrical RBN30 is a 20 Amp, Double Pole grid module with a black nickel rocker. Designed for appliances, there are additional engraved rocker covers from 'fridge freezer' to 'cooker' so all your appliance switches can be easily identified. Compatible with the BG Nexus Metal, and BG Screwless grid range, grid modules enable you to customise your own switch, by combining three elements, grid plate, grid frame and grid module.
