Overload Current Protection Characteristics

Test procedure Type Test Current Initial State Tripping or Non-tripping Time Limit Expected Result Remark
a B,C,D 1.13In cold t≥1h no tripping
b B,C,D 1.45In after test a t<1h tripping Current in the 5s in th increase of stability
c B,C,D 2.55In cold 1s<t<60s tripping
d B 3In cold t≤0.1s no tripping Turn on the auxiliary switch to close the current
C 5In
D 10In
e B 5In cold t<0.1s tripping Turn on the auxiliary switch to close the current
C 10In
D 20In
The terminology  “cold state” refes to that no load is carried before testing at the reference setting temperature.
