Why Choose the ABB CT1M-2 80 Current Transformer?
The ABB CT1M-2 80 is a through-primary 80/5 A current transformer designed for indirect measurement of electrical network parameters. Supplied under ABB order code 2CSG280245R1000, it converts a rated primary current of 80 A into a proportional 5 A secondary current for compatible energy meters, ammeters and multifunction measuring instruments.
Part of ABB's CT1M current-transformer range, the CT1M-2 80 is designed in accordance with IEC 61869-2. This model provides a best accuracy class of 0.5, with a rated burden of 1 VA at class 0.5, 2.5 VA at class 1 and 3 VA at class 3, providing flexibility for electrical metering and monitoring applications.
The CT1M-2 80 uses a compact through-primary design for installation around the monitored conductor. Its standard 5 A secondary output allows it to be paired with compatible measuring equipment, making it suitable for commercial and industrial switchboards, distribution panels and energy-management installations requiring indirect current measurement.

Reliable Indirect Current Measurement for Metering Systems
Current transformers allow electrical measuring instruments to monitor circuits carrying currents above their direct-input capability. The ABB CT1M-2 80 converts a rated 80 A primary current into a proportional 5 A secondary current, allowing compatible meters and instruments to perform indirect measurement without carrying the full primary current through the measuring device.
With class 0.5 accuracy available at a 1 VA burden, the CT1M-2 80 is particularly suitable where dependable current information is required for metering and energy analysis. Its standard 5 A secondary and IEC 61869-2 design make it a practical component for electrical distribution, load monitoring and energy-management installations.
Typical Applications
- Indirect electrical current measurement up to 80 A.
- Energy meters with 5 A current-transformer inputs.
- Ammeters and multifunction measuring instruments.
- Commercial and industrial switchboards.
- Electrical distribution and metering panels.
- Energy monitoring and load-analysis systems.
