3P 50hz 60hz 100A AC Molded Case Circuit Breaker MCCB

In globalized industrial and commercial facilities, electrical equipment often needs to face different grid standards of 50Hz or 60Hz. Protective devices designed specifically for a single frequency may cause protection characteristic drift and pose safety hazards in different frequency power grids. The SPX high-quality and customized 3P 50hz 60hz 100A AC Molded Case Circuit Breaker MCCB is developed to address this core pain point. It has been meticulously designed and calibrated to maintain completely consistent protection characteristics and breaking performance at both 50Hz and 60Hz frequencies, ensuring that your equipment's core three-phase power lines receive the same level of reliable protection no matter where it is deployed in the world.

The bimetallic strip thermal trip element has undergone special treatment and testing, and its inverse time overload protection characteristics are consistent under current thermal effects of 50Hz and 60Hz, providing precise overheating protection.
The durable 3P 50hz 60hz 100A AC Molded Case Circuit Breaker MCCB has high standard breaking capacity (such as 35kA, 50kA) and can safely cut off fault currents. The three pole linkage operation provides clear and reliable three-phase isolation points, ensuring maintenance safety.

Integrated into the control cabinets of machine tools, injection molding machines, packaging lines, and generator sets exported to countries with different grid standards, serving as the main power switch or motor protection unit.

Provide standardized protection for data center modules with global layout, three-phase precision air conditioning in communication base stations, and UPS input/output.
Used as a power distribution box for factory workshops, hotels, and hospitals, serving as a three-phase distribution main protection switch for floors or areas.

3P 50hz 60hz 100A AC Molded Case Circuit Breaker MCCB is suitable for three-phase grid connection or distribution protection that needs to be compatible with different generator frequencies in marine equipment, offshore platforms, and photovoltaic power stations.

Although the product is compatible with dual frequency, it is still necessary to confirm whether the rated voltage at the installation point is within the Ue range.

Accurately calculate the total load current and select a model with sufficient Icu value based on the expected short-circuit current level at the installation point.

If an adjustable model is selected, the long delay and instantaneous trip values should be set based on the precise current and starting characteristics of the load, and selectively coordinated with the upper and lower level protection equipment for calculation.

The installation of 3P 50hz 60hz 100A AC Molded Case Circuit Breaker MCCB must be carried out by a professional electrician according to the torque requirements provided by the manufacturer. After experiencing a severe short circuit, it is recommended to conduct professional testing.

When will you leave your factory and to have your spring festival holidays?
It is quite common for company administrative departments to take a two-week holiday during the Spring Festival, but workshop workers need to return to their hometowns for the holiday, so the holiday may be extended. This holiday arrangement is to allow employees enough time to reunite with their families and participate in the Spring Festival celebrations. Understanding company-specific holiday schedules and rest periods for shop floor workers is critical to coordinating work plans and project schedules. If you require more details, it is recommended to contact the relevant company contact directly to ensure that your plans are coordinated with the company's holiday schedule. I hope you and your team have a great time during the Spring Festival!

Do You have office in shanghai or guangzhou that i can visit?
Our company currently only has one production site, which is a common layout for production-oriented enterprises. we are able to more centralize resources and facilitate management and monitoring of production processes.

Can I only buy some spare parts from you?
We offer the option to purchase individual parts. This facilitates the replacement of components during product maintenance or allows for assembly line work as needed.

Can you send your equipment to my warehouse in guangzhou?
Certainly, feel free to reach out to any of your authorized agents to verify delivery details and ensure the secure and reliable delivery of your products.
