Mach-1™ DC Output Solid State Contactors

(rated up to 2,000V and 500A per module)

Mach-1™ Solid-State Contactors(SSC) are specially designed modular switches capable of switching medium to high power DC loads up to 500A per module.

Mach-1 SSCs utilize the latest semiconductor technology including SicFET/GaNFET. They had been used for many advanced applications including those from NASA, GM, and Rockwell.

Unlike electromechanical contactors, SSCs do not wear, do not arc, and is the the only switch you will need for decades to come!

For switching >500Amp, check out our modular MAX-Q Series, or our >1,000A DC Solid State Contactor Assemblies.

Frequently Asked Questions

Can your solid state contactors reliably switch high DC current?

Absolutely! We have 100's of high power solid state contactors in service across many industries, including automotive, automation, and scientific research,
Some applications operated at well over 1000 Amps and 1000 Volts DC..

How do I select the right voltage/current ratings?

You may also request our recommendations here, by completing a technical survey.
Or email us directly here.

It should be noted that different manufacturers may rate their devices differently, the following is a selection guidline for MaxQ and Mach1 Series DC contactors only.Solid State Contactor Selection Guide


How do I order?

Orders can be placed directly online here, or by sending us a RFQ via email on the product page.

Is this part UL certified?

We use UL certified parts only, from terminals, epoxy, to the semiconductor itself.
If external UL marking is required, we may be able to accommodate this via field certification or other means. Please contact us for more details.
