 AC operation, 50 Hz, standard version
- Switch-on power VA/cos ϕ 37 / 0.8
- Holding power VA/cos ϕ 5.7 / 0.25
 AC operation, 60 Hz
- Switch-on power VA/cos ϕ 33 / 0.75
- Holding power VA/cos ϕ 44 / 0.25
 DC operation
- Switch-on power = holding power W 4.0
Permissible residual current of electronics (with 0 signal)
 AC operation
1)
