Please recommend some domestic brands of motor protectors
Thread Content
I have been using thermal relay protection; now I want to switch to a motor protector. Could you recommend any reliable domestic brands? Thank you very much
Shanghai Huajian, Suzhou Wanlong, Beidou Galaxy, Zhuhai Youte, Jiangsu Jinzhi, Beijing Dewitt, Zhuhai Painuo
The domestically produced Beidou Galaxy is better; it generally doesn’t have any problems within 5 years, but false alarms may occur later on. This is mainly due to the aging of electrolytic capacitors, and component limitations affect the quality of these domestically produced products.
Our company first used Jiangyin Dongge, then Suzhou Wanlong, and now Zhuhai Painuo
Our facility uses ABB’s M102 series; we really want to switch back to thermal relays for comprehensive protection against all those weird faults – the workers simply can’t handle them, and engineers are the only ones who can deal with them. How many engineers can a factory have?
