Why Choose the ABB CT1M-10 3000 Current Transformer?
The ABB CT1M-10 3000 is a high-current 3000/5 A current transformer designed for indirect electrical measurement in low-voltage power distribution systems. Supplied under ABB order code 2CSG280595R1000, it forms part of the ABB CT1M current transformer range and provides a standardised secondary current for compatible metering and monitoring equipment.
With a rated primary current of 3000 A and a rated secondary current of 5 A, the CT1M-10 3000 converts high primary currents into a proportional signal suitable for electricity meters, ammeters, power analysers and energy monitoring systems. Its class 0.5 accuracy makes it well suited to applications where dependable measurement is required in commercial and industrial electrical installations.
The CT1M-10 format uses a through-primary closed-core design intended for installation around substantial busbars and conductors. This makes the CT1M-10 3000 particularly suitable for main switchboards, large distribution assemblies and industrial power systems where direct current measurement is impractical and a standard 5 A secondary signal is required.

Electrical meters and monitoring devices cannot normally accept the current flowing directly through a 3000 A power circuit. The ABB CT1M-10 3000 provides the required interface by transforming the primary current into a proportional 5 A secondary signal that can be measured by compatible instrumentation.
This indirect measurement arrangement enables high-current feeders and busbar systems to be incorporated into energy metering, power monitoring and electrical management systems. The CT1M-10 3000's class 0.5 accuracy makes it particularly suitable where reliable measurement of large distribution loads is required.
Typical Applications
- High-current electrical energy metering systems.
- Main low-voltage distribution switchboards.
- Large industrial power distribution panels.
- Busbar current measurement systems.
- Power and network monitoring installations.
- Building energy management systems.
- Industrial electrical measurement systems.
- Panel-mounted ammeters and power analysers.
