Hager | Invicta 250A TPN Distribution Board 72 Pole Chassis | IP30 Light Grey Steel
The Hager JVC7200S25TW is a 250A three phase and neutral distribution board from the Invicta range, built on a fixed load 72 pole chassis. The JVC7200S25TW takes 24 modules and mounts to the surface, measuring 1235mm high by 480mm wide by 135mm deep. The board carries an integral isolator switch and a key lock. The enclosure is powder-coated RAL 7035 light grey steel, rated IP30 for ingress and IK05 for impact, to isolation class I.
Switchboard capacity is the constraint that bites hardest on commercial fit-outs. A board specified to today's circuit schedule leaves nothing for the tenancy change, the extra mechanical services run, or the EV charger that arrives two years later. Ripping out an undersized board and re-terminating a live installation costs far more than specifying headroom at design stage. The JVC7200S25TW answers that with a 72 pole fixed load chassis rated to 250A and a 24 module capacity behind a single lockable door.
Contractors pricing switchboard work know the labour sits in the build, not the box. A board delivered with the chassis and isolator already fitted takes the bench assembly step out of the programme and shortens the time the switchroom is occupied. The fixed load chassis sets the circuit positions, so the layout is decided before the board leaves the wholesaler. A keylock door with two keys also closes out the access question on tenanted and multi-trade sites, where the switchroom is shared and the schedule needs protecting.
Features
- 250A rated current — the JVC7200S25TW is rated to 250A across the three phase and neutral chassis, suiting main switchboard and large sub-board duty.
- 72 pole chassis — 72 pole positions on a single chassis cover the circuit count of a commercial floor or a light industrial plant room.
- 24 module capacity — module capacity is stated at 24, setting the usable width available for circuit protection devices.
- Fixed load chassis — the busbar chassis is a fixed load type, so circuit positions come determined by the chassis rather than set out on site.
- Integral isolator switch — the board is supplied with one isolator switch already fitted, removing a separate main switch purchase and mounting operation.
- Key lock door — a single closed plain door locks with a key, and the JVC7200S25TW is supplied with two keys.
- IP30 ingress rating — protection against solid objects above 2.5mm with no water protection rating, which makes this an indoor board only.
- IK05 impact rating — the steel enclosure is rated IK05 against mechanical impact, appropriate to switchrooms and plant rooms rather than exposed positions.
- Powder-coated steel body — steel construction finished in RAL 7035 light grey, powder-coated for a consistent surface under switchroom conditions.
- Isolation class I — the JVC7200S25TW is a class I enclosure, so the steel body takes an earth connection as part of the installation.
- Not for outdoor use — the JVC7200S25TW is listed as unsuitable for outdoor positions, which follows directly from the IP30 rating.
Where to use
- Commercial switchrooms — main and sub-board duty on office, retail and hospitality tenancies where a 250A three phase supply feeds the floor.
- Light industrial plant rooms — the JVC7200S25TW suits factory and workshop distribution where machine circuits and building services share one board.
- Multi-tenancy fit-outs — the lockable door and 72 pole capacity suit shared switchrooms where several tenancies draw from one distribution point.
- School and institutional buildings — high circuit counts across classrooms, services and external lighting fit within the 72 pole chassis.
- Switchboard upgrades — the JVC7200S25TW replaces an undersized board where the circuit count has outgrown the existing chassis.
- Mechanical services boards — dedicated distribution for HVAC plant, pumps and controls, isolated at the board by the integral isolator switch.
The JVC7200S25TW is rated IP30 and is not suitable for outdoor use or for any position exposed to weather, wash-down or condensation. The IK05 impact rating suits a switchroom or plant room, not a trafficked or exposed location where knocks are likely. The board is isolation class I, so the steel body takes an earth connection as part of the installation.
