Single-phase efficient current transformers MC1

Product catalog summary

Overview
The document provides technical specifications and details for the MC1 range of single-phase efficient current transformers. These transformers are designed for measuring current in electrical installations and are compatible exclusively with CIRCUTOR’s MC range.

Specifications
The MC1 transformers offer a measurement range from 150 to 2,000 A with a secondary current of 250 mA. They feature three measurement ranges within the same transformer, which can be adjusted by changing the connection cable and the selected ratio in the measurement unit.

Applications
These transformers are suitable for installations where the electric supply can be interrupted for installation and are particularly useful in situations where the exact nominal current range is unknown.

Single-phase efficient current transformers MC1-1

Measuring current transformators and shunts MC1 Single-phase efficient current transformers Description The transformers of the MC1 range are efficient current transformers. This range of transformers offers a measurement range from 150...2,000 A. They operate with a 250 mA secondary and feature 3 measurement ranges in the same transformer: simply changing a connection cable and the ratio selected in the measurement unit. MC1 transformers are only compatible with CIRCUTOR’s MC range. Applications — In installations where the electric supply can be interrupted to install transformers. — Very useful for installing in places where the exact nominal current range is not known.
