Are 12 switched circuits not enough because you also need to protect permanently active consumers? The STV 311/5 offers 11 switched plus 5 unswitched, fused circuits – 16 in total, ideal for larger boat projects with many continuous consumers such as bilge pumps or cool boxes.
Compared to the STV 412
The STV 412 offers 12 switched circuits but no additional unswitched circuits for continuous consumers. If you need this separation between switchable and permanently active consumers, the STV 311/5 is the more suitable choice.
At a Glance
- 11 switched circuits, thermal circuit breaker (E-T-A 1140), rated current 8 A (optional 4/6/10/12/16 A)
- 5 additional unswitched, fused circuits – ideal for continuous consumers

Developed and manufactured in Germany.
Frequently Asked Questions
What does "unswitched" mean for the 5 additional circuits?
These are fused but cannot be switched on or off via a rocker switch on the panel – ideal for consumers that need to remain permanently active, e.g., bilge pumps.
Isn't the STV 412 sufficient for me?
Yes, if all your consumers are to be switched. If you need additional permanently fused circuits, the STV 311/5 offers more flexibility.

FAQ
Yes, this is possible. For this, the required fuse size per circuit must be specified when ordering the switch panel.
Yes, before each switchboard, a main fuse must be integrated into the supply line to the switchboard near the battery.
Yes, all common sensors used in the marine and automotive sectors can be connected.
