RE: AD10's - Whats the biggest load you're switching?

["Roger" <roger@xxxxxxx>]

Not sure if AD10s have internal contact supression, but if not, then adding an RC (100ohm resistor, 0.1u Cap) or MOV (Metal Oxide Varistor) supressor will supress arcing, and premature contact failure. All the usual suppliers will sell these.

I had an enquiry from the site on switching a 2.5kW electric heater, I thought AD10s weren't reliable at switching this size of load...early failures in the relays etc?

 

Thanks

3kW Immersion Heater.

 

If you want to go above that then use a Contactor connected to an AD10 or for a cheaper and more reliable operation, a Contactor with a low voltage coil driven from HomeVision.

 

What do you want to switch ?
