Real Industrial Application Case

A large automotive parts manufacturing company in Southeast Asia upgraded its automated production line and the supporting water pump and fan motor control systems. The existing ordinary contactors in the workshop experienced frequent high-frequency start/stop, leading to contact aging and unstable switching, resulting in frequent equipment shutdowns and low production efficiency.

The company selected the GOTOELE AX50-30-11 100A AC Contactor 3 Pole 1NO+1NC Auxiliary Contact to replace outdated parts for the centralized control of 42 37HP industrial drive motors and workshop fluid transfer pump sets. After 12 months of continuous operation, the equipment's high-frequency switching performance remained stable, with no equipment downtime caused by contact or component failures.

Leveraging the linkage function of the 1 normally open and 1 normally closed auxiliary contact, the product can precisely cooperate with PLC control systems and thermal relays to achieve reliable overload protection, significantly reducing the risk of circuit faults. After the upgrade, the operational stability of the production line equipment improved by 35%, and the monthly maintenance cost of electrical components decreased by 28%, helping the company achieve efficient and low-consumption production. Currently, this product is widely used in multiple overseas production bases of the company.
