Product Description:
The Janitza CT24 series features low-power (333 mV) split-core current transformers, available with primary current ratings of 50, 75, or 100 A. Each model comes with either a 25 cm or 2 m cable. These transformers use a connector system instead of screw terminals, enabling quick and easy connection to the Janitza Module 800-CT24. This 24-channel current measurement module supports up to four units when paired with the UMG801.
Split-Core Design
The split-core design of the CT24 transformers allows for straightforward installation around live conductors, eliminating the need to shut down the system. This not only streamlines setup but also minimizes disruptions. The transformers are ideal for both new installations and retrofitting. The 50 A and 75 A versions are compatible with conductors up to 10 mm in diameter, while the 100 A model accommodates conductors up to 12.5 mm.
