The above series of thermal overload relays have set current setting level, free tripping mechanism, ambient temperature compensation, phase loss protection, and reset test functions. Suitable for motor protection with rated operating voltage up to or. The protection level of tripping level is in line with the standard, and the protection against hand contact is in line with European and international standards.
Provide a complete range of motor overload protection solutions. The series provides normal overload protection and
provides heavy load protection.
Mainly used to protect motors from overload or phase failure, and cooperated with a full range of contactors to protect three-phase motors with rated operating voltages up to AC or DC from overload or phase failure.

Working environment
Below the altitude, the altitude of marine and humid zone type products does not exceed
The surrounding medium temperature is not higher than +℃ and not lower than ℃. Marine products are ℃
Installation location The relative humidity of the air does not exceed +°C, and higher relative humidity is allowed at lower temperatures. Corresponding measures must be taken when condensation occurs on the product due to temperature changes
The relative humidity of marine-type products does not exceed the temperature + ℃, and there may be salt spray and mold in the workplace
Humid tropical type The relative humidity of the product air at +℃ does not exceed
The pollution level of the installation site is level
In a medium with no explosion hazard and where there is no gas or conductive dust in the medium that is sufficient to corrode metal and destroy insulation
br/> In a place where there is no rain or snow.
