Real-World Application Cases

Case 1: Upgrade of a Southeast Asian Automotive Parts Manufacturing Plant

This factory experienced frequent shutdowns due to aging circuit breaker failures. In 2024, it selected 86 GOTEELE HGM 3P 250A and 400A circuit breakers for stamping and conveyor belt motor control.

Application Results: Stable motor start-stop, short-circuit response ≤10ms, production line continuous operation rate reached 99.9%, monthly losses reduced by over $90,000, and procurement costs reduced by 35%.

Case 2: European PV Energy Storage Power Station Support

A 50MW PV energy storage power station in Europe by 2025 selected 32 HGM 3P 630A units for inverter and grid connection point protection, requiring high breaking capacity, wide temperature range, and remote control.

Application Results: Stable outdoor operation for 12 months without failure in temperatures ranging from -20℃ to +55℃, withstanding current fluctuations and facilitating safe grid connection of the power station.

Packaging and Delivery

The HGM 3P/250A MCCB 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: How to select the rated current? What is the relationship between the rated current and the motor power?

A1: Select according to the motor's rated current and starting current. Commonly compatible models: 100A (32KW), 160A (55KW), 200A (75KW), 250A (90KW), 400A (160KW), 630A (315KW), 800A (560KW); for heavy loads/high-frequency start/stop, it is recommended to select one level higher.

Q2: Can the HGM Style Moulded Case Circuit Breaker 3P 100A - 800A be used in high-temperature environments? Will it affect performance?

A2: Standard operating temperature is -25℃ to +60℃. Its high-temperature material design ensures long-term stable operation, with protection curve drift ≤ ±8%. For temperatures exceeding 60℃, a derating of 10%-15% is required for each 10℃ increase in temperature, or customization is necessary.

Q3: What accessory expansions are supported? Will they affect protection performance?

A3: It supports modular expansions such as auxiliary contacts, time delay timers, and remote operating mechanisms. No modifications to the main body are required, and core protection performance is not affected. Interfaces conform to international standards.
