EASTRON SZL-ESCT-T24-250A Cable Conversion Current Transformer 250/5A, 2.5 VA, Class 1, 24 mm Aperture 32016

Cable conversion current transformer for retrofitting existing installations without disconnecting the primary conductor. The EASTRON SZL-ESCT-T24-250A converts a primary current of 250 A into a secondary current of 5 A with accuracy class 1 and a rated burden of 2.5 VA. The 24 mm inner diameter accommodates cables or busbars up to that size, and the solid-core design ensures reliable, maintenance-free operation.

Advantages

Retrofit without interrupting the circuit: the split-core design is not required because the transformer is installed around the existing cable. The self-extinguishing polycarbonate housing provides mechanical protection and electrical insulation. Screw terminals allow secure connection of secondary wiring.

Suitable for

• Energy monitoring systems in industrial and commercial buildings
• Retrofitting ammeters, energy meters, or protection relays
• Installations with 250 A primary circuits and 5 A instrument inputs
