PriceList for MP-M3 AC380V, Three Phase, Motor Protector with CE Certification

Short Description:

The new type AS-21B Three phase overload motor protector with current protection is an innovative product from Taihua that has been specifically designed to provide reliable and effective protection for three-phase motors. This protector is an electronic type that features a trip level of 30 and comes with a range of advanced features that make it highly flexible and customizable.One of the most significant advantages of this protector is its main circuit that adopts the core-through current sampling method, combined with advanced electronic (integrated circuit) circuits. This combination makes it highly effective in detecting and responding to overcurrent conditions, which could result in damage to your motor. The device also features sensitive phase failure protection, which helps to prevent damage to the motor phase caused by voltage fluctuations.Another key feature of the AS-21B three-phase overload protector is its strong anti-interference ability, which enables it to operate reliably in harsh industrial environments. The device has also been designed to be highly flexible and customizable, with continuously adjustable current value and overload delay settings.In addition to these features, the AS-21B protector has excellent inverse time characteristics, which enable it to respond quickly to different levels of overcurrent to minimize motor damage. The device is also highly efficient, reducing energy consumption and operating costs over the long term.Overall, the new type AS-21B Three phase overload motor protector with current protection is an innovative and highly effective protective device that offers a range of advanced features for three-phase motor protection. Its reliable operation, strong anti-interference ability, and adjustable settings make it an ideal choice for a wide range of industrial applications, including manufacturing, logistics, and transportation.
