DCC Decoder Saver – 8-Pin Fused Protection Adapter

Help protect your DCC decoder if a motor fault causes excessive current draw.

A failed motor can damage more than the motor itself; it can also put your decoder at risk. The DCC Decoder Saver adds a compact, fused adapter between your locomotive’s 8-pin socket and its decoder, providing an additional layer of protection. It's only 60mm long, so you should be able to tuck it into most locos

Why fit a Decoder Saver?

• Built-in 750mA fuse: Designed to interrupt excessive current and help reduce the risk of decoder damage from a motor fault.
• Plug-in installation: An 8-pin plug at one end and an 8-pin socket at the other fit between your locomotive and its compatible decoder.
• Compact size: Approximately 60mm long, allowing installation inside suitable locomotives where space permits.
• No soldering required: Plugs into a compatible existing 8-pin installation.

Check compatibility before ordering

For compatible 8-pin DCC-ready locomotives and 8-pin decoders, with sufficient internal space for the adapter and wiring.

Installation

Remove from track or switch off track power. Fit the adapter between the locomotive’s 8-pin socket and the decoder, observing the correct plug orientation.

Position the adapter and wiring clear of moving parts and ensure the body refits without trapping or pinching any wires.

Important information

The Decoder Saver provides additional fused protection. It does not guarantee protection against every motor fault, wiring fault or cause of decoder failure.

The fuse is not replaceable. If it blows, the adapter must be replaced and the underlying fault resolved before the locomotive is used again. But it will help save a very expensive DCC unit.

What’s included?

One DCC Decoder Saver adapter with an 8-pin plug, 8-pin socket and built-in 750mA fuse.

Locomotive and decoder are not included.

Replacement support

If your locomotive’s motor fails and the Decoder Saver’s fuse has operated, we’ll replace the adapter free of charge when we carry out the motor replacement.
