JR36 Thermal relay

Summarize

JR36 series thermal overload relays (hereinafter referred to as thermal relays) are suitable for overload and breakage protection of AC motors with 50HZ/60HZ, rated voltage 690V and current 0.25-160A for long-term operation or discontinuous long-term operation.

Thermal relay has broken phase protection, temperature compensation, automatic and manual reset, the product performance is stable and reliable.

This product conforms to: GB14048.4, IEC60947-4-1 and other standards.

This series of thermal relays can only be installed independently.

Normal working conditions

Altitude: not more than 2000m.

The ambient air temperature is -5℃~+40℃, and the average temperature within 24 hours does not exceed +35℃.

Atmospheric conditions: atmospheric relative humidity does not exceed 50% at +40℃, and relatively high relative humidity can be obtained at lower temperature. The average minimum temperature of the wettest month does not exceed +25℃, and the average maximum relative humidity of the month does not exceed 90%. Special measures should be taken for the condensation occasionally produced due to temperature changes.

The pollution level is level 3.

The inclination of the mounting surface to the vertical plane shall not exceed 5°.

In a medium without explosive hazard and in which there is no gas or conductive dust sufficient to corrode the metal and damage the insulation.

In places with rain and snow protection equipment and no water vapor.

Where there is no significant shaking, impact or vibration.
