RMB-644 Current Transformer Metering 0.6 kV
600 volt, indoor or outdoor, 10 kV BIL; single, dual, and multi ratios
The RMB-644 and RMB(X)-644 indoor/outdoor, window-type current transformers are rated for use on 600 volt systems with 10 kV BIL. Primary current ratios are available from 200:5 to 4000:5 at 60 Hertz (Hz) with a Rating Factor of up to 4.0. These dry-type, solid-cast current transformer swill operate with high accuracy for metering or relay applications.
The RMB-644 will operate with 0.3 Class accuracy for metering with burdens of B0.1 to B1.8 and up to C800 for some relay applications. The transformer is accurate through its Rating Factor, and can be used continuously to this level.
The RMBX-644 will operate with 0.15 Class high accuracy for metering applications with burdens of B0.1 to B1.8. The transformer maintains 0.3 accuracy from 1% of Inom through its Rating Factor, and can be used continuously to this level (for 0.15 accuracy range, see ratings specific to each ratio).
