DekaNewton and kiogram-force on an electromagnet

 There was an electromagnet operated by a keypad on the door.

I was interested in the label "300 daN".

Turns out daN stands for dekaNewtons 1 daN = 10N. I was thinking that it was simpler to write 3000N when I came across the idea of kilogram-force. On the surface of the Earth 1 kg mass has a weight of 10N to 1sf due to gravitational attraction. So by writing 300 daN, I assume that means that it could support a load of 300 kg pulling downwards on it. That quite a few of me. Sideways, the max load appears to be 100 kg. DekaNewtons are used to make an easier force to mass conversion under surface gravity on Earth.
