四、复位性能 Replacement performance
热继电器在动作后应能可靠复位。额定电流在63A及以下的热继电器，其自动复位时间不大于5min，手动复位时间不大于2min；额定电流63A以上的热继电器，其自动复位时间应不大于10min，手动复位时间应不大于6min。
The thermal relay ought to reliably be replacement after the movement.The ratedl current in 63A or below thermal relay,its automatic reset time is not over 5min,the manual replacementtime is not over 2min;The rated current is above 63A thermal relay,its automatic reset time should | | |
