The trip classes usually considered and most commonly used are 10A –10 – 20 – 30 referred to the time “Ti”. It is quite common speaking of normal starting and associate to it the trip classes 10A and 10, or of heavy starting making reference to the trip classes 20 and 30.
The limits fixed for “Ti”, which is the generic tripping time of the thermal protection, have the following meaning:
- the lower limit represents the minimum time under which the relay mustn’t trip in order not to interfere during starting;
- the upper limit is the time within which the relay shall surely trip.
[ABB]Наиболее часто применяют тепловые реле с классом расцепления: 10A, 10, 20 и 30, определяемым временем расцепления Ti. Для электродвигателя, выполняющего пуск в нормальных условиях, применяют тепловые реле с классом расцепления 10А или 10, а в тяжелых условиях – с классом 20 или 30.
Пределы, установленные для параметра Ti (типичное время расцепления устройства тепловой защиты), означают следующее:
– нижний предел представляет собой минимальное время, в течение которого реле не должно сработать и дать возможность выполнить пуск двигателя;
– верхний предел представляет собой время, в течение которого реле должно обязательно сработать.
