Energy Management
3-phase current transformers
Type TCD1M
Product description
Group of three split-core
miniature current sensors
to be used in combination
with EM271 energy meter.
Equipped with an RJ11 wire
for a very fast installation.
The energy meter automati-
cally reads from TCD1M its
primary current rated value,
saving time for the user set-
up. It can be mounted di-
rectly on the cables whose
current is to be monitored,
without need to interrupt the
load power supply.
