RDL-400SCT-1MC Compact Split Core Current Transformers (Set of 3), 1m, 400A
The RDL 400SCT-1MC belongs to the RI-CTS036 Series, which is part of a comprehensive family of split-core single-phase moulded case current transformers manufactured by Rayleigh Instruments.
The RDL 400SCT-1MC features a primary current input range of 400A and monitors current flow in commercial, industrial, or utility applications. It can connect to standard metering or relay products that require a 5A or 1A output.
One of the key advantages of the RDL 400SCT-1MC is its ease of installation. It can integrate into existing plants without removing busbars or cable lugs. Additionally, the transformer case includes clear markings to indicate the correct direction of primary current flow, minimizing the risk of installation errors.
