JR29 Series Thermal Relay

JR29-16

1. Application
JR29 series thermal overload relay is mainly suitable for A.C.electric power system with volt-age up to 660V, current up to 500A, 50/60Hz. It is generally used for the protection of overload and phase-lacking in circuits with three-phase induce motors and is often made up electromag-netic starters with CJX8 series A.C. contactors. The product conforms to IEC60947-4-1 stardand. Noter: JR29-16 is manually reset automatic to the other.

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?°C
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?°C
2	1.15	0	<2h	Heat state (Following the No.1 test)
