RDL 400/5A Split Core Current Transformer (50x80mm Aperture) – Set of 3
RDL 400/5A Split Core Current Transformer
This set of three split-core single-phase current transformers can be used to monitor the current flow in commercial, industrial, and utility plants. The RDL 400/5A Split Core Current Transformer is designed to be easily installed into existing systems without having to remove busbars or cable lugs. Furthermore, to minimise installation errors, it features clear markings on a moulded case that indicate the correct direction of the current flow. The RDL 400/5A Split Core Current Transformer can be connected to any standard metering or relay instrument requiring a 5A output. It has a primary current input range of 400A and features a 50x80mm aperture.
