The Camille Bauer SC40-B, item U118L, is a split-core current transformer for measuring alternating current in electrical distribution systems. The opening design supports installation around existing conductors and is particularly useful in retrofit projects in switchgear and distribution cabinets.
This version has a rated primary current of 250 A and provides a rated secondary current of 1 A. The resulting ratio is 250/1. The connected measuring instrument must have an appropriate secondary input, and the installation must follow the selected metering circuit design.
The rated burden is 0,2 VA. The specified accuracy class is 0,5. These parameters determine whether the combination of transformer, secondary wiring and instrument is suitable for the required measurement.
The transformer is intended for use with compatible energy meters, power monitors and network measurement equipment. It can support energy-flow documentation, current-load monitoring and the extension of existing measurement points.
The conductor and cable arrangement must fit the mechanical aperture. The SC40-B design has documented inner dimensions of 18 x 19 mm and an aperture of 18 mm. Selecting the correct version therefore requires consideration of both electrical range and the available installation space.
Installation planning must follow the relevant rules for insulation, secondary wiring and safe handling of current transformer circuits. Assembly and commissioning should be carried out by qualified electrical personnel with verification of the complete metering chain.
Item U118L identifies the specific combination of 250/1, 0,2 VA; class 0,5 within the SC40-B series. It can therefore be distinguished from versions with different primary currents, secondary currents or physical dimensions.
