The New Dorman Smith Loadlimiter 63 M Ultra TP&N Distribution board system is designed for applications demanding up to 250A incoming supply and up to 63A outgoing capacity.

These new boards are specially designed to install our new MAR Series 6kA 1-Pole AFDDs directly onto the busbar system, along with MCB and RCBO devices. Our KAR Series 10kA 3-module AFDD devices can be housed in a matching Service Centre and fed from corresponding MCB mounted on the busbar.

An upgraded design allows easier installation of modular devices such as surge protection and metering integral to the boards. Our Factory Built Assembly Department offers a bespoke L2 compliant Power & Lighting board system.
