D - Platform

The D – Platform consists of direct switching power relays designed for heavy-duty applications in demanding markets such as power utilities, petrochemical industries, and mining. The range includes 4 and 8 contact models with pull-in times of less than 20 milliseconds, while fast switching models achieve less than 7 milliseconds. Their robust construction and patented contact topology ensure minimal contact bounce and reliable operation under extreme conditions.
