Introducing the Fusebox ADRBTPN 1 Module TPN DIN Rail Blank – Space Filler for 3-Phase Distribution Boards available at SparksDirect.co.uk for the best price.
The Fusebox ADRBTPN is a single-module blank accessory designed to mount on a DIN rail inside a TPN (Triple Pole and Neutral) distribution board or consumer unit. In electrical panels, unused device spaces can make installations look untidy and may lead to poor cable organisation. The ADRBTPN fills these unused slots to create a neater, safer, and more professional-looking board layout.
Unlike circuit-carrying devices like miniature circuit breakers (MCBs) or residual current devices (RCDs), this blank simply occupies physical space — there’s no electrical functionality, but it improves installation quality and helps maintain proper spacing between live devices. It is especially useful in three-phase TPN systems where arranging MCBs, RCBOs, and spacers correctly matters for compliance and heat dissipation.
Made from robust insulating plastic with an IP20 rating, the ADRBTPN provides basic mechanical protection for internal distribution board components against accidental contact while maintaining easy access for authorised electrical work.
This accessory is a practical choice for electricians and contractors working on commercial, industrial, or larger domestic three-phase electrical installations, where unused ways are often present and need to be safety-blanked off.
Features and Benefits
- Single-module blank – occupies 18mm width on a DIN rail for standard spacing.
