The motor comprehensive protector is a motor protection device that integrates low-voltage protection functions such as overload protection, phase loss protection, over-voltage protection, locked-rotor protection, leakage protection, grounding protection and three-phase unbalance protection. It is an ideal substitute for traditional relays, and has the advantages of high precision, sensitive action, stable performance, power saving and environmental protection. Generally, motor protectors are composed of current sensors, comparison circuits, single-chip computers, relays and other parts.
The common intelligent integrated motor protector can have multiple function settings. When the user is in use, he can choose to set the corresponding protection parameters and protection functions according to the operating conditions of the on-site motor circuit. At the same time, when users choose the motor protector they need, it is best to put the product quality first, compare its performance and price differences, so as to choose the most suitable protector to reduce the inefficiency such as misoperation during actual use. The protection status. If the working environment of the equipment to be protected by the motor protector is often struck by lightning, you can also choose the one with lightning protection function.
In addition to the conventional protection functions, there are also some integrated motor protectors with specific protection functions. For example, fault recording, communication, remote control, remote alarm and output, etc., realize computer networking, and simultaneously detect the working effects of multiple motors. Of course, some manufacturers with R&D teams can also customize your own motor protector according to your actual situation.
