The arc suppression system is designed for electric circuits containing inductive loads with switching devices such as relays and thyristors.
The RC protection is connected in parallel with the two output contacts of the relay or in parallel with the thyristor to counteract the effects of the induced EMF that can damage the relay or thyristor.
- RC absorption circuit absorbs the induced EMF from the load,
- varistor prevents excessive voltage or current fluctuations,
- too high voltage or current values may damage relay contacts,
- protects the system against interference

Your previous questions regarding this product
I have a problem with a 24V DC fan burning out and welding shut the contacts of the relay that switches it on. Will this product help quench the arc? The motor is 24V DC, it draws 17A on start up and draws 6A when running.
Yes, this is what this module has been designed for. But first make sure your relay is rated for at least 20A (30A recommended).
