MC100A AC Magnetic Contactor 3P 100A 55KW 150A

GOTOELE is a professional supplier deeply involved in the R&D and production of low-voltage electrical equipment and industrial control equipment. With years of industry experience and mature manufacturing processes and a strict quality control system, GOTOELE has launched the MC100A AC Magnetic Contactor 3P 100A 55KW 150A, suitable for medium-power motor control.

This three-phase contactor has a rated power of 55KW and a maximum current carrying capacity of 150A, perfectly adaptable to the control needs of 32KW/37HP AC motors. Compared to ordinary civilian contactors, this product has been specifically optimized for high-frequency start-stop and continuous operation conditions, enabling stable operation in complex and harsh environments such as production workshops, automation systems, and distribution cabinets. As a high-quality industrial component made in China, it combines industrial-grade reliability with high cost-effectiveness, fully adapting to the needs of global industrial automation scenarios.

Core Advantages:

1. Stable High-Frequency Operation, Less Prone to Failure

Addressing the industry pain points of frequent start-stop of industrial motors and the aging and burning of traditional contactors, the MC100A contactor adopts an optimized electromagnetic structure and high-precision contact materials, capable of withstanding high-frequency switching operations for extended periods. This effectively avoids contact burning and poor contact, eliminating equipment downtime due to contactor failure and ensuring continuous and stable operation of the production line.

2. Adaptable to Harsh Working Conditions

The MC100A AC Magnetic Contactor 3P 100A 55KW 150A boasts excellent dustproof, anti-interference, and anti-aging properties. It can operate stably for extended periods in dusty, temperature- and humidity-fluctuating factory workshops and electromechanical equipment environments, providing reliable circuit switching and protection for industrial production equipment, significantly reducing the negative impact of environmental factors on equipment operation.

3. Wide Compatibility and High Cost-Effectiveness

While achieving industrial-grade high performance, this contactor offers extremely high cost-effectiveness. It is compatible with mainstream industrial control systems such as PLCs and frequency converters, and flexibly adapts to various scenarios including motor drives, water pump units, and HVAC equipment. It is widely applicable to global industrial OEM projects, effectively reducing enterprise equipment procurement and subsequent maintenance costs.

Real-world Industrial Application Case

A conveyor belt production line of an automated machinery manufacturing company in Southeast Asia has long faced the problem of a high failure rate of its supporting contactors. Ordinary contactors are prone to contact burnout and circuit instability under long-term high-frequency start-stop conditions, leading to frequent unplanned production line shutdowns, low production efficiency, and high maintenance costs.

In 2025, the company replaced all its old equipment with GOTOELE MC100A AC Magnetic Contactor 3P 100A 55KW 150A. After six months of continuous operation verification, the product's high-frequency operation optimized design perfectly matches the continuous start-stop requirements of conveyor belt motors, and its dustproof and durable characteristics are suitable for high-dust workshop conditions. The overall failure rate of the production line equipment decreased by 80%, the number of unplanned shutdowns was significantly reduced, and the overall production efficiency increased by 15%. At the same time, the product's stable performance reduced the workload of parts replacement and maintenance, significantly reducing the company's operating costs. It is currently being used in batches for multiple OEM supporting equipment for the company and exported to industrial projects in multiple regions.

Packaging and Delivery

The LC1-D6511 32KW 37HP AC Contactor uses standard export cartons to effectively prevent damage during transportation. 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.
