The Voron BOM, as of the 25th of May 2022, requires an “Omron G3A-210B-DC5 SSR” as the Solid State Relay for controlling the bed heater
The SSR this refers to is actually the NA model shown on Omron’s website here. G3A doesn’t exist apparently.
Many kits come with a G3NB-210B which is very similar but has a max rated throughput of 220V whereas the NA is rated for 240V
Also note that the 10 amp rating, at up to 40°C on the G3NA, is only when it has a heatsink attached according to the Omron website. Dont forget your fans in the skirt.
In the UK a 5A SSR is probably sufficient for a 750W heater as at 240V AC this will equal 750W / 240V = 3.125A
In the US this will be doubled based on the 110V mains voltage
