Starter Solenoid Current Rating

[Aunkst]

I have a need for a intermittent duty, DC contactor. Voltage will be low, but current is relatively high (500A),

What is the DC Current rating of an average starter solenoid? These devices are not typically supplied with data sheets, just an applicable vehicle model name.

Any leads would be great, Thanks.

100-150 amps, roughly.


It is very dependent on all sorts of details.

My first thought is a contactor from an electric fork lift. I'm not sure what the current rating is, but the batteries are 36, 48, 72 or 80 Vdc and the drive motors are 15-30hp.

Have you researched White Rogers contactors?

Their data sheets show the continuous and inrush ratings. If you need the time versus current curves, contact their engineering tech support.

This 200 amp continuous duty rated contactor has a 600 amp inrush rating.
