Do you own an aluminum or steel boat? Then the two-pole version is mandatory, not optional: The STV 203-2p protects 3 circuits with galvanic isolation – this protects your hull from stray current corrosion, which is a real risk with single-pole panels on metal boats.
Compared to the STV 203
For GRP boats, the simple, single-pole STV 203 version is sufficient. For metal boats, the two-pole version is the safer choice.

Frequently Asked Questions
Why is the two-pole version important for metal boats?
It prevents galvanic corrosion from stray currents that can flow through the hull in single-pole systems.
Is the single-pole STV 203 version sufficient for me?
Only on GRP boats – for aluminum or steel, the two-pole version is the safer choice.
