2CSG280695R1000 ABB CT1M-12 6000 Current Transformer 6000 A/5 A

Why Choose the ABB CT1M-12 6000 Current Transformer?

The ABB CT1M-12 6000, order code 2CSG280695R1000, is a 6000 A/5 A through-primary current transformer designed for indirect measurement of electrical parameters in high-current metering, monitoring and energy management applications. Part of ABB's Metering Accessories range, it transforms a high primary current into a standardised 5 A secondary current for compatible electricity meters, network analysers and measuring instruments.

As part of the ABB CT1M current transformer series, the CT1M-12 6000 is designed according to IEC 61869-2. Its large through-primary aperture is designed for substantial horizontal busbars, making it particularly suitable for industrial distribution equipment, main switchboards and other high-current electrical systems.

With a 6000 A rated primary current, 5 A rated secondary current and accuracy class 0.5, the CT1M-12 6000 provides a 6000:5 transformation ratio for accurate indirect electrical measurement. It delivers 100 VA at class 0.5, 100 VA at class 1 and 100 VA at class 3, while accommodating a horizontal busbar cross-section up to 125 × 93 mm.

Reliable Indirect Measurement for Very High-Current Electrical Systems

Current transformers allow meters and measuring instruments to monitor electrical circuits carrying currents above their direct measurement range. The transformer produces a proportional secondary current, allowing electrical parameters to be measured without routing the full primary circuit current through the connected measuring instrument.

The ABB CT1M-12 6000 converts a nominal 6000 A primary current into a 5 A secondary current. Its class 0.5 accuracy, 100 VA class 0.5 output and large 125 × 93 mm horizontal busbar aperture make it particularly suitable for accurate indirect current measurement in high-capacity industrial distribution systems, main switchboards and energy monitoring installations.

Typical Applications

• High-current electrical energy metering systems.
• Industrial power distribution installations.
• Main distribution switchboards and electrical panels.
• Indirect measurement of circuits with a 6000 A nominal current.
• Energy monitoring and management systems.
• Current measurement with compatible network analysers, meters and instrumentation.
• Large horizontal busbar current measurement.
• Industrial panel-building and electrical instrumentation applications.
