Co-ordination type 1 and type 2
The co-ordination typologies admitted by the Standard with reference to the behavior of the protection device against short-circuit towards the starter components are classified as “type 1” and “type 2”.
Under short-circuit conditions, the coordination of type “1” allows the contactor and the overload relay to be damaged; as a consequence they could not be able to operate without repairing or replacement of parts. However, the Standard prescribes that these devices do not cause damages to people or installations, for example with parts of the components ejected outside the enclosure.
Under short-circuit conditions, the coordination of type “2” allows the risk of contact welding, provided that the contacts themselves can be easily separated (for example through a screwdriver) without important deformations.
This type of coordination requires that the contactor or the starter do not cause damages to people or installation and that they are able to resume operation after restoring of the standard conditions.
[ABB]Координация типа 1 и 2 с аппаратом защиты от короткого замыкания
Стандарт определяет два типа координации компонентов пускателя с аппаратами защиты от короткого замыкания: тип 1 и тип 2.
Координация типа 1. В условиях короткого замыкания допускается повреждение контактора и теплового реле, в результате чего они могут оказаться непригодными для дальнейшей эксплуатации без ремонта и замены частей. При этом данные устройства не должны создавать опасности для людей и оборудования, например, вследствие вылета частей пускателя из оболочки.
Координация типа 2. В условиях короткого замыкания допускает сваривание контактов при условии, что они могут быть легко разъединены (например, отверткой) без заметной деформации. Контактор или пускатель не должны создавать опасности для людей и оборудования и должны оставаться пригодными для дальнейшей эксплуатации после восстановления нормальных условий.
