Length
5 m

This is the Victron 100A:50mA current transformer for MultiPlus-II and MultiGrid-II units, with a 5 m cable ending in bare wires. It is used for PowerControl and PowerAssist, and for optimising self-consumption with external current sensing. The CTR12 series has wire ends, while the CTR11 series has a jack connector, so the part number tells you which type you are getting.

Our take

The 100A:50mA ratio sets what current this transformer can sense, and the wire-end 5 m lead means you connect it with bare wires rather than a jack. It feeds PowerControl and PowerAssist on a MultiPlus-II, so match the ratio and connector type before fitting.

From our buying guide

On a boat subpart I covers, an electrical component must not ignite fuel vapor around it unless it is isolated from gasoline fuel sources. Ignition protection is the maker's statement.

Check before you buy:

  • 33 CFR 183 subpart I applies to boats that have a gasoline engine, except an outboard, so a gasoline generator counts.
  • On a boat subpart I covers, each ungrounded output conductor from a battery needs a manually reset, trip-free circuit breaker or fuse within 72 inches of the battery.
