Sizes S00 to S3 for screw and snap-on mounting onto TH 35 standard
mounting rails, size S3 also for TH 75 standard mounting rails.
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.
4)
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.
