The following limit values are indicated:
1)
Resistance between housing and mains plug for connector cables up to 5 meters long
2)
0.1
Ω
is added for each additional 7.5 meters of cable length, up to a maximum of 1
Ω
3)
For protection class I devices with activated heating elements
(if heating power > 3 kW and R
ISO
< 0.3 M
Ω
: leakage current measurement is required)
4)
This limit value refers to all-pole switches (corresponds to doubling the limit value or cutting actual
measuring current in half)
