4 FAQs about [Minsk energy storage dc contactor selection]

How to choose a contactor based on a datasheet?

Most of the contactor manufacturers share necessary information in datasheets. Thus, a wise approach would be making a comparison table to cover basic specifications like thermal and mechanical initially. After pre-selection based on datasheet values, we should consider system specifications.

How many volts can a DC contactor handle?

Compact DC contactor (2 make contacts) up to 1,500 V for frequent switching under load. Designs with 200, 750 or 1,200 volts of rated voltage; insulation voltage up to 1,600 volts; continuous current up to 120 amps. DC contactor for battery voltages up to 48 V (80 volt Ui). Four sizes up to 60, 100, 150 and 240 A.

Why should battery designers design busbars based on contactor capacity?

The current carry performance reduces at higher temperatures and with a lower cross-section of busbars. Therefore, battery designers should design busbar or cable sizes according to contactor capability. “ GV240 Series “, Gigavac LLC, 2018, accessed 07 Jan. 2022.

How does temperature affect contactor selection?

Temperature affects contactor selection significantly. Contactor manufacturers make tests to specify how the temperature affects contactor performance. The current carry performance reduces at higher temperatures and with a lower cross-section of busbars.
