The BG Electrical Nexus Metal NBS83 is a British General NBS83 400W 2-Way Push 3 Gang Intel Dimmer. This brushed stainless-steel triple (3 gang) two-way dimmer light switch is rated at 200W. Manufactured by British General Electrical, the NBS83 is a trailing edge dimmer switch suitable for domestic or commercial settings requiring variable light levels for LED, halogen, CFL, and incandescent lAs. With a slim modern profile at only 44mm deep, softly rounded corners, and a versatile brushed stainless-steel finish, it complements a wide range of interior decor. The lightly lacquered surface reduces fingerprint impressions, ensuring a clean appearance even with repeated use. The NBS83 offers smooth, noiseless dimming and accommodates lower-wattage lAs to prevent flickering. Equipped with BG's soft start technology, it brings lAs to a preset light level in a second, extending their lifespan. The dimmer switches also safeguard against overloading by automatically adjusting power to lights or transformers if overloaded, ensuring consumer safety. These switches fit into existing mounting boxes (minimum 25mm box depth) and include an integrated moisture-controlling gasket for installation in recently plastered walls without tarnishing the finish. Backed by a 25-year guarantee, the NBS83 is a reliable choice. Maximum LED Load: 5-100 Watts. Compatible with trailing edge lAs and BG Luceco lAs. Features a Push On/Off rotary dimmer switch and requires a 25mm metal wall box. Supplied with Colour-coded fixing screws.
