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.
