The CA-SCT24I-200A-L080 is a single-channel split-core current transformer rated at 200A, with a Φ24mm aperture. Its split-core construction lets it be fitted around an existing conductor, which suits retrofit metering work where the circuit cannot easily be disconnected.Supplied with an 8 m lead, this CT is intended for use with the iWSN and iXN series. The maximum input voltage is 500VAC at 50/60Hz. Accuracy is rated at 1% for the CT alone, and at ±3% or ±0.3A when used with the iWSN-1110X, iWSN-1131P, iWSN-750P and iWSN-757P.Choose this variant when you need a 200A-rated CT with a Φ24mm aperture and an 8 m lead for iWSN or iXN metering installations.ApplicationsEnergy managementPower meteringCurrent monitoring on iWSN and iXN series installations
CA-SCT24P-200A-L040-3P is a set of three split-core current transformers designed for clamp-on current measurement in energy management installations. The 24 mm aperture accepts conductors without disconnecting the circuit, and the 4 m leader cable connects each transformer to the power meter.Choose this model when your measurement range sits around 200A and you are using a compatible PM-series meter. It is rated for a maximum input current of 200A, a minimum of 0.15A, has a 1% accuracy class and a 40:1 CT ratio. The set is compatible with the PM-2133DP, PM-3133P and PM-4324(A)P power meters.Suits retrofit metering, where cables cannot be disconnectedThree transformers per set, one for each phaseApplicationsEnergy management and power meteringClamp-on current measurement on existing installationsMonitoring with PM-2133DP, PM-3133P and PM-4324(A)P power meters
The CA-SCT36I-400A-L080 is a single-channel split-core current transformer for energy management and power metering. Its Φ36mm opening takes conductors up to a 400A rating, and the split core fits around an existing cable without disconnecting the circuit.This variant is specified for use with the iWSN and iXN series. The 8 m wire gives room to route the sensor from the conductor to the measuring device. Accuracy is 0.5% for the CT alone, and the source lists a combined accuracy of +-3% or +-0.3A when used with iWSN-1110X, iWSN-1131P, iWSN-750P and iWSN-757P.Single-channel split-core CT for retrofit installation400A rating through a Φ36mm apertureMaximum input voltage 500VAC, 50/60HzApplicationsEnergy managementPower metering with iWSN and iXN series devices
CA-SCT36P-300A-L040-3P CR is a split-core current transformer for measuring up to 300 A on conductors with a 36 mm inner diameter. Its split core clamps around an existing cable, so circuits can be metered without disconnecting the load.The transformer is designed to pair with the PM-2133DP, PM-3133P and PM-4324(A)P power meters. Its 0.5% accuracy and 60:1 CT ratio make it the 300 A option with a 36 mm aperture, suited to larger conductors than the 10 mm, 16 mm and 24 mm versions in the same series.Each order includes three transformers, each with a 4 m leader cable.ApplicationsEnergy monitoring and sub-meteringCurrent measurement on larger conductorsPower metering with PM-series power meters
CA-SCT36P-400A-L040-3P is a split-core current transformer that clamps around an existing conductor without disconnecting the circuit, so it can be fitted to live installations.
