330 Datasheet — Zinc Anode

When you open a , the first section you will encounter covers the physical dimensions. These numbers are critical for installation teams who need to ensure the anode fits the designated space on the hull or skeg.

You can estimate the life of a Zinc Anode 330 using the formula: zinc anode 330 datasheet

Using the datasheet’s consumption rate, you can calculate lifespan: [ \textLifespan (years) = \frac\textAnode mass (kg)\textCurrent (A) \times \textConsumption rate (kg/A·yr) ] Example: A 2.0 kg zinc anode 330 driving 1.0A → 2.0 / (1.0 × 11.2) ≈ . When you open a , the first section

Only if salinity is consistently above 15 parts per thousand. Below that, zinc may form a passive layer. Switch to an aluminum alloy anode. Only if salinity is consistently above 15 parts per thousand

Do not use zinc anodes in freshwater . They passivate (form a hard white crust) and stop working. Use magnesium or aluminum anodes for fresh or low-salinity water.
