a contactor and an overload relay or a monitoring relay as a completely assembled three-
part combination. If this should nevertheless be necessary, the following restrictions apply:
Motor starter protector + contactor + electronic overload relay / 3RR monitoring relay
(size S00 / S0)
Thermal restrictions
No restrictions
Motor starter protector + contactor + electronic overload relay / 3RR monitoring relay
(size S2)
Thermal restrictions
•
•
Motor starter protector + contactor + solid-state overload relay (size S3)
Thermal restrictions
On request
Motor starter protector + contactor + thermal overload relay (size S00 / S0)
Thermal restrictions:
Reduce permissible ambient temperature by 20 K
No side-by-side mounting
(≥ 10 mm clearance for vertical installation, > 20 mm for
horizontal installation)
Current derating to 87 % of I
Motor starter protector + contactor + thermal overload relay (size S2 / S3)
Note
A three-part combination consisting of a motor starter protector, a contactor and a thermal
overload relay is not permissible for sizes S2 and S3.
