With the suitable terminal brackets
(see "Accessories", page 5/50),
the
3RU11 overload relays for direct mounting can also be installed as stand-
alone units.
Size S00 for screw and snap-on mounting onto TH 35 standard mounting
rail.
Observe maximum rated operational current of the devices.
Guide value for 4-pole standard motors at AC 50 Hz 400 V. The actual
starting and rated data of the motor to be protected must be considered
when selecting the units.
