Instrument, 600 Volt Class Voltage and Current Class 4210 / Refer to Catalog 4210CT9701 Voltage and Current Transformers ● Schneider Electric offers voltage, current, and bushing instrument transformers. ● Square D® 600 volt rated voltage and current transformers are field proven in well over a million installations, where accuracy and longer, more dependable operation are essential. ● Typical applications for instrument transformers are: indoor, switchgear assemblies, motor controllers, over power transformer bushings, over circuit breaker bushings, metering, relaying, and current sensing. Voltage Transformers Schneider Electric offers three models of voltage transformers, each suited for a particular application. ● Model 450R is designed for applications requiring accurate voltage measurement within the 0.3% accuracy class. Model 450R is ideal for switchboard use with 1% instrumentation ● Model 460 is designed for voltage indication where accuracy is less critical or where burden requirements are low. Model 460R is ideally suited for use with transducers and panelboards and other monitoring applications. ● Model 470 is designed for extremely accurate voltage measurement where a very low burden is to be used. Examples of such applications include the input to PLC modules and other electronic devices with a high input impedance. Current Transformers Current transformers are low cost, compact units that offer good electrical performance in a general purpose transformer. ● They are very easy to mount on the conductors. ● All current transformers feature permanent polarity marks molded into the case. Type of CT available: ● General purpose ● Torroidal (single ratio) ● Rectangle window (single ratio) ● Split core ● Bushing (single ratio) (multi-ratio) Part number listing is available in the Supplemental Digest.
