1.Application
JRS2 thermal relay is suitable for AC 50/60Hz, voltage up to 660V and current up to 630A,general AC motor of long or discontinuous long operation, used as overload protection and hasthe functions of breaking phase protection, temperature compensation, and trip indication. Itcan automatically and manually get back. It can be fixed with contactor CJX1 together, also beindependtly fixed. The product conforms to IEC60947-4-1 stardand.

2. Motion Characteristic: Three-phase Balance Motion Time

No	Times of the setting current	Motion time			Start condition	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 of the setting current		Motion time	Start condition	Ambienttemperature
	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)
