Tronic 250A Three Phase Distribution Board with 4 Pole MCCB

Our review

This is a ready-made three-phase distribution board from Tronic, built around a 250A four-pole MCCB as the incomer and rated for 400V. It offers four outgoing ways, each able to take a 32A to 100A TPN MCCB, so it suits a small commercial or light industrial installation where a handful of three-phase circuits need to be fed and protected from one enclosure. The Form 2b, Type 1 separation and the fitted digital multifunction meter and three phase pilot lamp are worth noting if you want metering and phase indication at the board itself. Before ordering, confirm your total load and the rating of the upstream supply, and check that the outgoing devices you intend to fit match the 32A-100A range and the physical space provided. Compare it with plain empty enclosures or boards supplied without an incomer: those can work out cheaper, but you then buy and wire the main breaker and metering separately. Also weigh it against larger-way boards if you expect to add circuits later. Available on Sokonia.
