Taihua Phase sequence overload manual reset motor protector AS-22C-2H

Short Description:

The AS22C-2H motor protector is a state-of-the-art product designed to ensure safe and reliable operation of three-phase motor applications across a wide range of industries. Built with advanced electronic technology, the AS22C-2H offers several features that make it an ideal choice for protecting motors with a range of power ratings between 0.5KW to 100KW.One of the most significant advantages of the AS22C-2H motor protector is its tripping levels. With five different options of 2, 5, 10, 20, and 30, the AS22C-2H is capable of detecting and responding to over-current conditions effectively. This adjustability provides optimal protection for motors that are subject to varying loads or operating conditions.In addition to over-current protection, the AS22C-2H offers several other protection functions such as current phase failure and overload protection. The sensitive phase failure function detects any imbalances between the three phases, thus preventing any further damage to the motor. The overload protection function comes with adjustable setting current and delay features that provide the necessary time to fix the overloading problem.The AS22C-2H motor protector is designed to offer reliable operation, with an advanced electronic circuit design and core-threading current sampling method. This results in highly precise monitoring of the motor’s electrical signals, detecting and addressing any irregularities or faults immediately.Another advantage of the AS22C-2H is its strong anti-interference ability. The protection technology ensures smooth and reliable operation, even in harsh industrial environments, by filtering out unwanted electrical signals.The AS22C-2H motor protector is also user-friendly, with adjustable settings to allow users to customize the device to their specific needs. Its good inverse time characteristics enable it to respond quickly and effectively to different over-current levels, ensuring maximum protection for any motor application.Overall, the AS22C-2H motor protector is a reliable and durable product that provides essential protection functions for your motors. It is easy to install, provides highly customizable protection, and is suitable for a range of industries and motor applications.
