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 The current steadily rises to
the specified valuewithin 5s
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 theauxiliary switch to
close the current
C 10in

Residual Current Operating Breaking Time

Type In/A I△n/A Residual Current (I△)Is Corresponding To The Following Breaking Time (S)
AC Type any
value
any
value
1In 2In 5In 5A,10A,20A,50A
