YUMO JR28s-25 Relay Socket Refrigerant Thermal Overload Relay Miniature Relay
Application:
JR28s series thermal overload relay are suitable for overload and phase-failure protection of AC motors with frequency of 50/60Hzvoltage up to 690v, current up to 01-93A under 8-hours duty or uninterrupted duty.Functions provided by these relays, are phase-failure protection, ON/OFF indication, temperature compensation, and manualautomatic reset.International standard: IEC 60947-4-1The relays can be mounted onto contactors or installed as single units.
Normal Working Conditions and Installation Conditions:
Altitude: no more than 2000m
The ambient air temperature is -5°C+40 C, and the average temperature within 24 hours does not exceed +35°CAtmospheric conditions At +40C, the relative humidity of the atmosphere does not exceed 50%, at lower temperatures, there canbe a higher relative humidity, the monthly average minimum temperature of the wettest month does not exceed +25°C, themonthly average relative humidity also the maximum relative humidity is not more than 90%, and the condensation on theproduct due to temperature changes is considered
The pollution level is level 3
The inclination of the mounting surface to the vertical surface does not exceed 5°.In a non-explosive hazardous medium, there is no gas in the medium that is sufficient to corrode metals and destroy insulationand where conductive dust exists.
In place where is no significant shaking, shock and vibration.
