Contactors with extended operating range
6.10.1
Contactors for rail applications according to IEC 60077-2
These contactor types are equipped with electronic coil control.
The following conditions of use apply:
● They are approved for operation within the temperature range -40° C to +70° C.
● The operating range of the contactor operating mechanism is 0.7 - 1.25 x U
s
referred to
the rated value for operation on DC voltage.
● The operating mechanisms with rated voltages of 24 V DC, 72 V DC and 110 V DC are
available by preference.
● Like the solid-state operating mechanisms of the 3RT1 standard contactors, the operating
mechanisms in the sizes S6-S12 are equipped with 2 operating modes for direct control.
