multict ASK

Bushing type current transformer

Measure, Current transformer

multict ASK

The current transformers in the multict ASK series are set apart by their compact size, versatility, and higher safety standards.

 

Compactness

All transformers in this series have a depth of 30 mm. The different designs offer different windows for different cable and bar diameters.

 

Versatility

A primary rail clamp with a positive guide is available for fastening the transformer to primary rails. If necessary, for example in conditions with tight space, the connection terminal can easily be pulled out.

 

Description

Bushing type current transformers for primary rated currents between 30 A and 7,500 A, secondary rated current 1 A, 5 A, in accuracy classes 0.2s, 0.2, 0.5s, 0.1, and 1. All transformers are delivered including the the materials necessary for fastening. The supply of primary conductor rails (electrolyte copper, nickel-plated) in accordance with the rail window is optional, including DIN 933 screws, complete with nuts, washers, and spring rings for mounting in busbars or similar.

 

Application:

An affordable and compact alternative for setting up new systems.
