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.
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.
2)
3)
Maximum protection by fuse for overload relay, type of coordination 2.
For fuse values in conjunction with contactors, see "Technical
specifications" --> "Short-circuit protection with fuses/motor starter pro-
tectors for motor feeders", see note on Technical Information on page 5/1.
For overload relays > 100 A, see 3RB2.
