Altivar 312 Variable Speed Drives Page 28 Short Circuit Current Ratings

28 Altivar 312 variable speed drives Short Circuit Current Ratings The combinations in the tables have been tested per UL508C (Reference UL file E116875). These ratings are in addition to ratings on the nameplate of the product. The values for the overcurrent protection devices are the maximum allowable amp size. Smaller amp ratings may be used. Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit protection must be provided in accordance with the National Electrical Code and any additional local codes. The devices are not provided with thermal protection of the motor. A sensing of motor overtemperature is required to be provided by the end user. 167F (75C) copper conductor with the AWG wire size shown on nameplate for all sizes. Suitable for use on a circuit capable of delivering not more than __X__ rms symmetrical kiloAmperes, __Y__ Volts maximum, when protected by __Z1__ with a maximum rating of __Z2__ .
