Assembly of three-part combinations with link module between the motor starter protector and the
contactor
You are basically advised to refrain from setting up combinations of a motor starter protector,
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
Mechanical restrictions
No restrictions
DIN rail adapter required
Motor starter protector + contactor + electronic overload relay / 3RR monitoring relay
(size S2)
Thermal restrictions
Mechanical restrictions
