LR2-D13 thermal overload relay 17A-25A1,Professional manufacturer of thermal relay.2,For overload protection...

1.LR2-D series thermal relay i ssuitable for using in the circuits rated voltage up to 660V,rated current 93A AC 50HZ or 60HZ,for over-voltage protection of AC motor.The relay has differential mechanism and temprature compensation and can plug CJX2(LC1-D)series ac contactor.

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)
