Reading the specification
What these numbers mean for your installation
A datasheet tells you what the unit does. This is what each figure changes about how you specify, feed and site it — worked out for the 200 kVA specifically, not the range in general.
278 A per phase
At 415 V three-phase, 200 kVA works out at roughly 278 A per phase. At 278 A you are normally into parallel cable runs per phase rather than a single conductor. Confirm the terminal chamber accepts the number of runs your cable schedule calls for — discovering it does not, on the day of commissioning, is the most common reason installations at this rating slip.
300V–470V
The unit holds output at 415V ±1% anywhere between 300 V and 470 V in. Pulling a 300 V supply back up to 415 V means adding 115 V — a 38% lift on the incoming supply, with the series winding carrying roughly 55 kVA of the 200 kVA throughput. Below 300 V it runs out of range, and the answer is a wider-window build, not more kVA.
< 20 ms
At this rating the stabilizer is feeding a whole section of the floor, so < 20 ms determines whether one machine's inrush propagates into every other machine on the same board. That is the mechanism behind most "random" tripping complaints we are called out to.
150% for 30 minutes
Direct-on-line starting draws six to eight times full-load current for a few seconds, and 150% for 30 minutes is the margin that absorbs it. At 200 kVA the practical constraint is usually the largest single motor rather than the total: size against that starting current, not against the sum of the nameplates.
Sizing Guide
When is 200 kVA the right choice?
200 kVA is the standard stabilizer size for a mid-size CNC machining cluster — four to six VMCs with toolchangers, plus a coordinate measuring machine, deburring station, and shop floor lighting. It is also the first size where many plant engineers specify remote monitoring as a requirement, because at this scale an undetected fault causing extended under-voltage can damage hundreds of thousands of rupees worth of tooling. The 200 kVA unit is specified for data centres with 100–150 servers when the facility runs a 2N power topology and wants a stabilizer on the utility incomer before it splits into two UPS feeds.
Before you order
Where 200 kVA goes in, and what the site needs
Typical installations
We supply 200 kVA most often into large manufacturing facilities, steel mills, cnc machining centers and textile mills, alongside paper manufacturing and power distribution substations. What separates those sites is duty cycle rather than load. A rating that runs cool on single-shift work sits near the top of its thermal range on a continuous three-shift line, and that is the point at which oil cooling stops being optional.
Site preparation
At 800 kg this is forklift work, and the forklift has to be rated for 800 kg at the extended reach that placement requires. Confirm floor loading before it arrives — a ground-floor workshop slab is normally adequate, a mezzanine generally is not. Leave working clearance on the terminal side for cable entry and inspection. Sustained ambient above 45 °C, or an enclosed room without cross-ventilation, requires derating — send us the room conditions and we will confirm the rating still holds where you intend to put it.
Adjacent ratings
If 200 kVA is not the right size
Sizing rarely lands exactly on a catalogue rating first time. These are the ratings either side of it in the same range — compare the specification before you commit.
