Real-World Application Cases

Case 1: Production Line Upgrade at a Southeast Asian Automotive Parts Processing Plant

The plant's original production line experienced frequent motor contactor burnouts, resulting in a high failure rate under high-frequency start-stop scenarios and impacting production efficiency. In 2024, the plant replaced the existing equipment with the GOTOELE LC1-E4011 18.5KW 30HP AC Contactor, compatible with an 18.5KW stamping motor, which operates over 500 high-frequency start-stop cycles daily. To date, the equipment has experienced zero failures, withstands workshop dust and temperature fluctuations, reduces production line downtime by 90%, and lowers maintenance costs by 60%, becoming a benchmark case for core equipment upgrades in the plant.

Case 2: Automated Sorting System for a European Logistics Warehouse

This sorting system requires remote control of multiple 15-20KW conveyor motors. The contactors must have remote control and overload protection functions, and be compatible with the existing control modules. The project adopted the GOTOELE LC1-E4011, paired with thermal relays and auxiliary contact modules, to achieve precise control and safety protection for the motor group. The equipment is compatible with 400V AC, 50Hz operating conditions, has been running stably for over 12 months, and is compatible with the existing system architecture, helping the project successfully pass international OEM acceptance standards.

Packaging and Delivery

The LC1-E4011 18.5KW 30HP AC Contactor uses standard export cartons to effectively prevent damage during transportatio. Bulk orders have a delivery time of 10-15 days. OEM brand customization is also supported; logo printing and customized packaging designs can be provided according to customer needs to meet the brand promotion requirements of different markets, providing efficient and convenient delivery services to global customers.

FAQ

Q1: Can the LC1-E4011 operate stably for a long time under 60Hz high-frequency conditions?

A1: Yes. This product is specifically designed for 50/60Hz dual-frequency operation. Its core components have undergone high-frequency aging tests and can operate stably in a 60Hz environment for extended periods, withstanding frequent switching shocks and adapting to industrial scenarios with different frequency standards worldwide.

Q2: What is the range of motor power that the LC1-E4011 is compatible with? Can it support higher power motors?

A2: It is standardly compatible with 18.5KW (30HP) AC motors and can handle 32KW (37HP) motor control scenarios. For higher power motor compatibility, please contact the GOTOELE technical team for customized selection solutions.

Q3: How does the LC1-E4011 18.5KW 30HP AC Contactor achieve overload protection? What accessories are required?

A3: The LC1-E4011 itself does not have overload protection; it needs to be integrated with a matching thermal relay. The thermal relay monitors the motor operating current in real time and triggers the contactor to disconnect in case of overload, protecting the motor. Additionally, auxiliary contact modules can be added as needed to achieve protection signal feedback and interlocking control.
