Shanghai Jastar Industrial Co., Ltd.
Three-phase · 380 V · up to 26 kW 12,000 / 26,000 W 380 V 30 – 55 °C OEM / ODM

12 / 26 kW Three-Phase Instant Electric Water Heater — AC 380 V, Commercial Duty

A three-phase unit for whole-house and light commercial supply. Rated 12,000–26,000 W on AC 380 V, it runs several outlets at once — a bathroom, a kitchen and a laundry point from one machine, with the outlet held between 30–55 °C. Available with a stainless steel cup or a cast aluminium element. Because it is three-phase, 26 kW draws well under 40 A per phase; the 40 A leakage breaker is in the box.

Why this model

Three-phase power, whole-building duty

12 to 26 kW on AC 380 V — sized for whole-house and light commercial supply.

AC 380 V, 12 – 26 kW

AC 380 V, 12 – 26 kW

Rated 12,000–26,000 W on a three-phase 380 V supply. Three-phase distribution keeps the current per phase low, so the supply cable stays at ≥ 6 mm² copper core.

Three panel finishes

Three panel finishes

White, black and a brushed silver front are offered on the same body, so one SKU covers a range of interior specifications.

Mounts at any angle

Mounts at any angle

Whole-house and light commercial

Whole-house and light commercial
