1.Application

JR30 series thermal relay is used in the circuit of 50/60Hz, rated insulation voltage 660V,rated current 0.1-85A for protecting the phase break when the electric motor is overloaded. Therelay has different mechanism and temperature compensation. It can be plugged in CJX5 seriesAC contactor. The product conforms to IEC60947-4-1.

2.Motion Characteristic: Three-phase Balance Motion Tim

No	Times of the setting current(A)	Motion time			Start conidition	Ambient temperature
1	1.05	>2h			Cold state	20±5oC
2	1.2	<2h			Heat state (Following the No.1 test)
3	1.5	<4min
4	7.2	10A	2s< Tp ≤10s	≤63A	Cold state
		10	4s< Tp ≤10s	>63A

3.Phase-losing Motion Characteristic

No	Times the setting current(A)		Motion time	Start condition	Ambient temperature
	Any two phases	Another phase
1	1.0	0.9	>2h	Cold state	20±5oC
2	1.15	0	<2h	Heat state(Following the No.1 test)
