300 KVA Servo Stabilizer — Three Phase, Oil Cooled
300 KVA · Three Phase

300 KVA Servo Stabilizer Manufacturer in India

The 300 KVA Servo Stabilizer is a three phase servo voltage stabilizer that holds your output at a precise 415V/230V ±1%, however wide the incoming supply swings. Servo Stabilizer India builds every 300 KVA unit to order — oil-immersed for 100% continuous loading and harsh ambient conditions — and supplies it factory-direct across India with installation and AMC. It is sized for heavy industrial plant — furnaces, rolling mills and full-factory main lines.

How to size a 300 KVA servo stabilizer

A 300 kva servo stabilizer is rated to deliver 300 KVA at the output. As a rule we keep 20–25% headroom above your connected load, so a 300 KVA unit is the right choice for a working load of around 240 kW. That margin absorbs the starting surge of motors, compressors and pumps without the stabilizer running hot or tripping. If your load includes several large motors that start together, send us the list — we'll confirm whether 300 KVA is enough or whether to step up to the 400 kva servo stabilizer.

At 300 KVA the oil-immersed for 100% continuous loading and harsh ambient conditions. It is supplied as a three phase 415V unit with independent phase control, so it corrects each phase separately even when the incoming supply is unbalanced. Read our KVA sizing guide or air vs oil cooled comparison for more detail.

300 KVA Servo Stabilizer FAQs

The price of a 300 kva servo stabilizer depends on the phase (three phase), cooling type (oil cooled) and input voltage window you need. Servo Stabilizer India builds each 300 KVA unit to order and sells factory-direct — no dealer margin. Share your load and we send a same-day quotation. Call +91 81788 87426.

A 300 KVA servo stabilizer comfortably runs a connected load of about 240 kW — we keep 20–25% headroom for motor starting surges so the unit stays cool and lasts longer. It suits heavy industrial plant — furnaces, rolling mills and full-factory main lines. Send your machine list and we confirm the right rating.

The 300 KVA Servo Stabilizer is a three phase (415V, 4-wire) unit — standard for industrial loads of this size. For smaller single phase requirements we also build ratings up to 15 KVA.

On a three phase 415V supply the approximate full-load current is 417 A per phase. We size the input/output MCCB and bypass switch accordingly.
