TCA21 200/250A/5A Current Transformers
SOCOMEC current transformers deliver at the secondary a normalized current proportional to the primary current and adapted to the size of the associated device.
Measuring sensors from 5 to 5000A.
TCA21 200/250A/5A Current Transformers
SOCOMEC current transformers deliver at the secondary a normalized current proportional to the primary current and adapted to the size of the associated device. They are equipped as standard with removable terminal cover, double terminals to short-circuit the secondary without risk.
They are fixed by two metal legs to screw, or some, by a fixing on an enclipsable DIN rail. Connections are made by screws or fast-on lugs.

benefits
Adapted accuracy class
In order to make better use of your DIRIS data loggers and COUNTIS energy meters, we offer a range of current sensors with several accuracy classes: 0.25; 0,5; 1 or 3.
Wide choice of sizes and dimensions
Optimize your measurement chain regardless of your size needs, available space, conductor size or accuracy class. All combinations are available, as standard or on request.
Quick and easy editing
Current transformers are suitable for any type of assembly: field, flat, DIN rail, or platinum. Implementation is quick and easy.
