Model Number: MZFR-H-3000W Key Specifications/Special Features: Ceramic heating element for solater water heaterSize: 47mmVoltage: 220V 50/60 HzPower: 1500WInsulation electric strength: 2,500V, 50Hz at room temperature, no punch-through in one minuteLeakage current: ≤0.025mA under normal operating condition,≤10mA in water after brokenAcid corrosion resistance: boil for 6h in 5% sulfuric acid solution, corrosion rate <10g/m2.hAlkali corrosion resistance: boil for 6h in 30% NaOH solution, corrosion rate <0.6g/m2.hLife: 5000hrsCeramic electric heater specially designed for solar water

High energy efficiency-with high thermal conductivity ceramic, 20% higher energy efficiency ceramic, 20% higher energy efficiency was achieved compared with traditional heater
Guaranteed safety-heating wire- will be oxidized immediately when the ceramic is broken, producing leakage current much lower than body safety value (10mA)

Corrosion resisting: no need for corrosive-resistant coating, silicon nitride ceramic has excellent anti-acid/alkali properties, never rust
