Learn more by watching our NLS 30257 | 24 Pole Surface Mount Switch Board | IP40 video.
The NLS 30257 is a 24 pole surface-mount switchboard enclosure rated up to 100A at 250/415V, built for Australian domestic and light commercial distribution. The 30257 takes up to 24 single-pole DIN modules across two rows and carries an IP40 rating for indoor, dry locations. It is manufactured by National Light Sources to IEC 60439-3 and ships as a complete kit with DIN rail, earth bar, neutral links, and pole fillers.
A crowded sub-board or a shed supply frequently needs more ways than a small enclosure accommodates, without consuming additional wall space. The 30257 arranges 24 poles across two rows in a compact configuration, leaving room to route conductors and complete terminations without cramming the board. Its DIN rail accepts most major breaker and RCD brands, so the board can be populated with protection devices already carried on the van. The smoke-tinted door gives an immediate read of breaker positions once the board is live.
For contractors, the 30257 is a cost-effective sub-board that keeps job pricing competitive on sheds, granny flats, and small commercial fitouts. The complete kit removes the need to source separate DIN rail, copper links, or pole fillers before installation begins. Because the enclosure accepts 18mm modules from most manufacturers, existing shelf stock drops straight in, which simplifies quoting and inventory. It remains a straightforward, good-looking board that does the job on domestic work without inflating the bill of materials.
The NLS 30257 is rated IP40 and is not weatherproof. Do not install the 30257 in exposed outdoor positions, damp areas, or wash-down zones. It must be mounted indoors or in a dry, protected location, and it ships empty of protection devices, so it is not a ready-to-use consumer unit on its own.
