Motor phase overload protector (DZ15D adjustable)
DZ15D motor protection is the lack of motor phase, overload protection, the motor overload, lack of phase to be protective measures, with adjustable function. Mainly used in fans, pumps, motors and other load control and protection.
Protector integrated motor pump all-round protection technology, the use of micro-processing chip as the core computing unit, the operation speed, high reliability, and has a perfect communication and analog transmission output capacity. To provide comprehensive aspects of the motor protection, reliable performance, easy to operate, but easy to install and maintain. Protection range and sensitivity than the thermal relay high, can effectively avoid motor burnout, thermal relay is not action, is the thermal relay ideal upgrade products.
Scope of application
In daily use, cause the motor burned mainly for the following reasons:
◎ contactor for a phase of the impact of contact arc wear, resulting in motor phase loss.
◎ submersible pump, sewage pump for water pumping finished, the pump is not a short period of time cooling and burning.
◎ pump for a long time do not rust stuck, or sand impounded impeller burned.
◎ motor due to internal bearing wear and stuck caused by stall.
◎ motor overload burned for a long time.
◎ burned by overheating or under-voltage caused by motor heating.
The above is the main cause of the motor burned, RC15-40 series of intelligent protector in modern industry, the phenomenon of motor burned apparent protection, and thus to the production unit to facilitate.
◎ Elevation: The altitude of the installation site is not more than 2000 meters.
◎ Ambient temperature: the upper limit is not higher than +40 ℃, the lower limit of not less than -5 ℃.
◎ relative humidity: not more than 70%.
◎ no significant shaking and shock vibration of the place.
◎ no explosion hazard of the medium, and the media is not enough to corrode and destroy the insulation of the gas and conductive dust place.
◎ no rain and snow invasion of the place.
