LR2 Thermal Overload Relay

LR2 Thermal Overload Relay can be used with LC1 contactor as Magnetic starter, also can be install as single unit

LR2 Thermal Overload Relayare suitable for overload and phase-failure protection of AC motors with frequency of 50/60Hz, voltage up to 690V, current up to 0.1-150A under 8-hours duty or uninterrupted duty. Functions provided by these relays, are phase-failure protection, ON/OFF indication,temperature compensation, and manual/automatic reset. Applicable Standards: National Standard: GB 14048. International Standard: IEC 60947-4-1 The relays can be mounted onto contactors or installed as single units.

2. Motion Characteristic: Three-phase Balance Motion Time

No	Times of the setting current	Motion time			Start condition	Ambient temperature

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)
