Frame Fixed-Type Circuit Breaker

1. The Frame Fixed-Type Circuit Breaker is tailor-made for power distribution networks with AC 50Hz, 60Hz, rated working voltage of 400V to 1140V, and rated current of 200A - 6300A.

2. The Frame Fixed-Type Circuit Breaker is responsible for distributing electric energy, protecting lines and power supply equipment. It can effectively resist common power faults such as overload, undervoltage, short circuit, and grounding. It is a key equipment to ensure the safe, stable and efficient operation of the power system.

3. The Frame Fixed-Type Circuit Breaker is widely used in industrial production, energy exploitation and transmission, commercial buildings, and infrastructure construction, providing a solid guarantee for the power needs of global customers.

1. Sturdy structure and strong breaking capacity: The Frame Fixed-Type Circuit Breaker adopts an innovative three-dimensional frame structure, which independently encapsulates the contact system and the arc extinguishing chamber, greatly improving the electrical performance and reliability of the product. Its short-circuit breaking capacity can reach up to 150kA, and it can withstand a short-time withstand current of 100kA. When a short-circuit fault occurs, it can quickly cut off the current, effectively protecting power equipment from the impact of strong current.

2. High-quality materials to ensure long-term stable operation: The key components of the Frame Fixed-Type Circuit Breaker are made of silver-plated contacts and high-temperature resistant materials, which reduce contact resistance, reduce heat loss, and improve the electrical conductivity and high-temperature resistance of the equipment. The mechanical life is not less than 10,000 times. Even in harsh environments such as high temperature, humidity, and dust, it can ensure long-term stable operation, reduce the frequency of equipment replacement and maintenance, and lower the use cost.

3. Personalized customization service: A variety of rated current (200A - 6300A) and voltage (380V/660V/690V) options are available. At the same time, it supports front/back panel wiring methods, and can also customize tripping curves according to customers' special needs to meet the personalized needs of different projects.

4. Convenient maintenance design: The Frame Fixed-Type Circuit Breaker has a reasonable structural design, which is convenient for maintenance personnel to carry out daily inspections, repairs and replacement of components. The simple and clear operation interface and clear marks reduce the difficulty of maintenance, improve maintenance efficiency, and ensure that the equipment returns to normal operation in the shortest time.

1. Strict quality inspection process: From the moment raw materials are put into storage, every link is under strict quality control. The raw materials are tested in terms of dimensional accuracy and electrical performance to ensure their quality meets the standards; during the production process, random inspections of semi-finished products are carried out to control production quality.

2. Before leaving the factory, the finished products undergo comprehensive electrical performance testing, mechanical performance testing, intelligent function testing, environmental adaptability testing, safety certification testing, as well as appearance and structure inspection. Only the Frame Fixed-Type Circuit Breakers that pass all inspections are allowed to enter the market, ensuring that each frame circuit breaker delivered to customers has excellent performance and reliable quality.

3. Efficient logistics system: SDKC has established an efficient logistics system in close cooperation with professional logistics partners. Every link from the offline of the Frame Fixed-Type Circuit Breaker to the delivery to customers is carefully arranged to ensure that the products can be delivered quickly and safely, meeting the urgent needs of customers and reducing the impact of delayed supply on project progress.

Q: How do you package the frame circuit breaker?

A: We use wooden box packaging (in line with international export standards) to effectively protect the products from collision, moisture and other damages during transportation, ensuring that the products arrive at customers safely.

Q: How to install the Frame Fixed-Type Circuit Breaker?

A: Fixed-type circuit breakers are usually installed in power distribution cabinets or switchgear. It is necessary to ensure firm installation, correct wiring, and sufficient heat dissipation space to ensure the normal operation and good heat dissipation of the equipment.

Q: What is the wiring method of the Frame Fixed-Type Circuit Breaker?

A: The upper end is connected to the power supply, and the lower end is connected to the load. Cables or busbars that meet the specifications must be used to ensure reliable connection.

Q: How about technical support?

A: We will provide you with installation instructions and/or videos, and professional engineers will be responsible for communicating with you at any time.

Q: How does the Frame Fixed-Type Circuit Breaker provide short-circuit protection?

A: When a short circuit occurs in the circuit, the frame circuit breaker will trip quickly to cut off the power supply, preventing equipment damage and fire.

Q: What product tests are done before leaving the factory?

A: The product tests that we conduct on the Frame Fixed-Type Circuit Breaker before leaving the factory include: electrical performance test, mechanical performance test, intelligent function test, environmental adaptability test, safety certification test, appearance and structure inspection, etc.
