Notes
General Conditions — Direct alignment in the block, all devices 100% operating factor, horizontal or vertical mounting.
Curve A — Maximum permissible continuous operating voltage U
max
with limiting continuous current on the contact side (see respective technical data).
Curve B — Minimum permissible relay operate voltage U
op
after pre-excitation
1
) (see respective technical data).
1
Pre-excitation: Relay has been operated in a thermally steady state at the ambient temperature T
U
with nominal voltage U
N
and limiting continuous current on the contact side (see respective
technical data) (warm coil). After being switched off for a short time, the relay must reliably pick up again at U
op
.
