Application and FeaturesAPPLICATION, FEATURES AND SELECTION CRITERIASquare D 600 Volt rated current and voltage transformers are field-proven in well over a million installations where accuracy and longer, more dependable operation are essential. In most cases, the information contained in this catalog should be sufficient for the proper selection of the instrument transformer best suited for your application. However, should you need additional assistance, please feel free to contact your nearest Square D Field Sales Office or contact our Nashville instrument transformers product marketing group. Application Instrument transformers are ideally suited in the following applications: Indoor Switchgear assemblies Motor controllers Over power transformer bushings Over circuit breaker bushings Metering Relaying Current sensing NOTE: Transformers listed in this catalog should not be applied to circuits having a phase-to-phase voltage greater than 600 volts, unless adequate additional insulation is applied between the primary and secondary windings. Square D assumes no responsibility for damage of equipment or personal injury caused by the transformers operated on circuits above their published ratings. Features High thermal ratings for short-time use. Most instrument transformers listed in this catalog are UL and CUL Recognized per Classification XODW2, File No. E100570. Manufactured according to rigid Square D quality control standards. Extremely wide range of ratios available. Wide range of window sizes from 1.13 in (28 mm) to 8.13 in (206 mm). Applicable standards are ANSI C57.13 and CSA C13. Models feature strong, molded thermo-plastic cases. Molded plastic core jacket ensures rugged core-to-winding insulation. Low energy loss, grain-oriented silicon steel annealed for optimum magnetic qualities. Most models feature permanent polarity marks molded into the case and large, easy to read ratios are clearly marked on the case. Rugged, corrosion-resistant mounting brackets are available as options. Most ratings are available from stock. Selection Criteria How to Select a Current Transformer 1. Determine that the primary range of the current transformer encompasses the application requirement. Lower or specialized ratios may be obtained by adding primary and secondary turns as shown on page 52. 2. Select the proper window size or slightly larger to fit your primary conductor. Refer to the table below. 3. Determine the usual application of current transformer that best suits the application for which it is intended. Refer to the table below. If the application requirements are not fully defined, refer to Burden and Accuracy Information on page 53. 4. After selecting a transformer, check its accuracy and burden capabilities by referring to the information page for that transformer.2 2001 Schneider Electric All Rights Reserved6/01

Selection Criteria and Selection ChartsHow to Select a Voltage Transformer Square D 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 460R 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 470R is designed for extemely accurate voltage measurement where a very low burden is to be used. Examples of such applicatons include the input to PLC modules and other electronic devices with a high input impedance. Current Transformers Selection ChartWindow Diameter IN1.3 1.56 1.94

Permanent polarity marks are molded into the case. Large, easy-to-read ratios are clearly marked on the case. Secondary terminals are #10-32 brass screws and include flat washers and bronze lockwashers for easier installation.Model 312R Designed for relaying and other current sensing applications.

Windings are completely distributed around the core on each tap, resulting in a low reactance on all taps. Mounting holes are provided for bolting the unit around a power transformer or circuit breaker bushing. Frequency: 60 Hz.
