Basler Electric 1783 DC Current Transformer Coil (1200:5A Ratio)

The Basler Electric 1783 (also referenced as BE1783) is a DC current transformer coil designed for accurate current measurement and protection in DC power systems. This coil provides a 1200:5A ratio, converting primary currents up to 1200 A down to a standard 5 A secondary signal for use with meters, relays, and control devices. It is commonly used in large DC contactors, battery banks, and electrochemical processes.

Constructed with a high‑permeability core and precision winding, the 1783 offers excellent linearity and low phase error. Its robust housing and insulated leads ensure safe operation in industrial environments.

Key Features

• Primary current rating: 1200 A DC

• Secondary output: 5 A (nominal)

• High accuracy: ±1% of reading

• Low burden for minimal insertion loss

• Designed for continuous duty

• Compact and lightweight construction

Technical Specifications

Ratio: 1200:5; insulation class: 600 V; frequency response: DC only; operating temperature: -25°C to +70°C; mounting: panel or busbar mount; secondary terminals: screw type.

Applications
