Energy Management 3-phase current transformers Type TCD3M • 3-phase current transformer set compatible to EM271 energy meter • Primary current 400 A • Hole size 20.5 mm • Auto-detection of the primary current rated value by the EM271 energy meter • For cable mounting • Umbilical connection to EM271 energy meter through RJ11 Product description How to order TCD3M400 80CM X Group of three split-core miniature currentsensors to be used in combination with EM271 energy meter. Equippedwith an RJ11 wire for a very fast installation. The energy meter automati- cally reads from TCD3M its primary current rated value, saving time for the user set- up. It can be mounted di- rectlyon the cableswhose current is to be monitored, without need to interrupt the load power supply.
