multict ECTB

Bushing type current transformers for billing purposes - screwless connection

Measure, Current transformer

multict ECTB

The current transformers for internal billing purposes from the multict ECTB series are suited for use in conjunction with an MID energy consumption meter.

The current transformer’s calibration period is indefinite.

 

Conformity

The conformity of transformers is documented by a yellow conformity mark and a declaration of conformity enclosed with the product.

 

Quality assurance

The quality assurance system must be recognized by the PTB in accordance with module D of the conformity evaluation procedure, so that billing transformers can be used directly for billing purposes. For other European countries, these design-approved current transformers are approved for billing purposes.

 

The current transformers from the multict ETCB series are also set apart by the “Cage Clamp®” screwless connection technology.

The springless connection technology with spring terminal makes connections gas-tight and maintenance-free. Thanks to the strong retaining forces, the current transformer can be used even in conditions of high mechanical stress (e.g. vibrations). The spring terminal is 2 designed for solid and flexible conductors up to a max. of 4 mm². This eliminates the need for ferrules.

Billing current transformers for current ranges from 25 A to 3,000 A in accuracy classes 0.2s, 0.2, 0.5s, 0.5.

 

Application

Establishing a measuring point, which is consulted for billing.
