Selection of AC contactors for high-power electric heaters

2019-02-10View Original

Thread Content

For high-power electric heaters (such as 1000kw), if AC contactors are used, their size will be very large. Is it possible to use other electronic components for control, such as thyristors?

The original poster can ask the electrical engineer at their own unit directly. Thyristors are control devices used for regulation, while contactors are switching devices. Nowadays, electric heaters can all be controlled using thyristors, whenever there is a need for it
