JRS1 Series Thermal Relay

1.Application
JRS1 series thermal relay is suitable for using in the circuits rated voltage up to 660V, ratedcurrent 80A, AC 50/60Hz, for over-current protection of AC motor. The relay has the differentialmechanism and temperature compensation and can plug in CJX2 series AC contactor. Theproduct 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	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)
