8.1.1 Max. load dependent on ambient temperature and line voltage.The maximum permissible temperature for the rated current at rated voltage is specifiedas rated temperature.Since the dissipation of the power loss (heat development) in the device is decisivelydependent on the ambient temperature, the max. load must be reduced at an ambienttemperature above the rated temperature ( following table)!The average value measured during a 24 h period must be 5 K under the max. ambienttemperature. For installation in a switch cabinet, the device’s dissipation and its possibleaffect on the ambient temperature must be taken into consideration!Since the power loss in the device increases with rising line voltage, the following tablemust be observed.Maximal load depending on line voltage and ambient temperature208 V (-15 %)...415 V (+6 %) over 415 V (+6 %)...480 V (+10 %)Type 40 °C 50 °C 55 °C 40 °C 50 °C 55 °CFRQS(5)-4A 4.0 A 4.0 A 4.0 A 4.0 A 4.0 A 4.0 AFRQS(5)-10A 10.0 A 8.0 A 7.0 A 9.5 A 7.5 A 7.0 AFRQS(5)-16A 16.0 A 13.0 A 11.0 A 14.5 A 11.5 A 9.5 AOperating Instructions FRQS-4/10/16A EnclosureL-BAL-E196-GB 1445 Index 002 Part.-No. 00163410-4224/27 |
