1.Application

CJX7 Series AC contactors are suitable for frequency of 50/50Hz,rated insulation voltage up to 690-1000V,rated operational current up to 7A-95A at rated operational voltage up to 380V under the utilization category AC-3, They are mainly used for making breaking electric circuits at a ling distance and for frequent staring stopping and reversing control of AC motos,They comply witch IEC947,VDE0660, GB14048.

2.Motion characteristic:three-phase balance motion time

NO	Set current cinles	Notion time			Start conidition	Temperature
1	1.05	>2h			cold state	20±5C
2	1.5	<2h			heat state (following the NO.1 test)
3	2.2	<4min
4	7.2	10A	2s<TP≤10s	≤63A	cold state
		10A	2s<TP≤10s	>63A

3.Phase-losing motion characteristic

NO	Set current cinles		Notion time	Start conidition	Temperature
1	Arbitrary two phase	Three phase	Notion time	Start conidition	Temperature
2	1.0	0.9	>2h	cold state	20±5C
	1.15	0	<2h	heat state (following the NO.1 test)	20±5C
