Contactors, Starters and Overload Relays

Technical Data and Speciﬁcations

Overload Relays

These tripping characteristics are the

mean values of the spread at 20°C

ambient temperature in a cold state.

Tripping time depends on response

current. With devices at operating tem-

perature, the tripping time of the over-

load relay reduces to approximately

25% of the read off value. Speciﬁc

characteristics for each individual set-

ting range can be found in

MN03402001E.
