10x38mm Ceramic Fuses

10x38mm Ceramic Fuses are ceramic tubular fuses that meet international standards. They are made of ceramic shells and contain fuses. They are commonly used for circuit protection of electrical equipment. The fuses are suitable for specifications of 10 mm in diameter and 38 mm in length. They are widely used in home appliances, industrial equipment, communication equipment and other fields. When selecting a model, it is necessary to select the appropriate model based on parameters such as the rated current, rated voltage and short-circuit capacity of the equipment. In addition, some models are equipped with visual indicators to facilitate users to judge the status of the fuse.

Transportation

This 38mm long fuse is quite important in the electrical systems of various vintage European cars and trucks; in the DC power supply protection context of ships, it can also consistently safeguard circuit safety.Whether it's an industrial-grade fuse box and distribution board, a battery management system (BMS) controlling battery charging and discharging, or an inverter turning solar energy into electricity, it must offer consistent overcurrent protection. Whether it's a battery management system (BMS) controlling battery charging and discharging, an industrial-grade fuse box and distribution board, or an inverter turning solar energy into electricity, it must provide consistent overcurrent protection.

1. Basic product specs Material technology:

The shell is high-strength alumina ceramic, which can withstand high temperatures above 150°C to ensure stable performance in harsh environments; the interior is filled with quartz sand to quickly suppress arcs at the moment of large current disconnection; the copper or brass end caps at both ends are nickel-plated and silver-plated to effectively enhance corrosion resistance; the fuse element is made of silver or copper alloy, which is precisely customized according to different rated currents to ensure the sensitivity and reliability of protection.

2.Performance of breaking
The normal specification model can safely shut off 10kA current in 250V AC or 32V DC environment; the high-performance version for industrial and energy fields has a breaking capability above 50kA. Even under high fault currents, the interior sand-filled ceramic shell construction lets it perform safe and dependable breaking operations.

3. Key International Standards

Breaking Capacity
• 150KA or 500V AC/DC (100mA-32A)
• 80KA at 690V AC/DC (100mA-32A)
• 50KA at 1000V AC/DC (100mA-32A)

Stable operation in high temperature environment
The 10x38mm Ceramic Fuse adopts a high-strength alumina ceramic shell that can withstand high temperature environments exceeding 150°C. This ceramic material has excellent thermal stability and mechanical strength, so that the fuse will not break when it is subjected to thermal shock in the circuit, ensuring the safety and reliability of the circuit breaking process. The internal quartz sand filling can quickly suppress the arc generated during disconnection and avoid damage caused by arc diffusion. The copper or brass end caps are treated with nickel silver plating to improve corrosion resistance and extend service life, ensuring continuous and stable protection of the circuit in complex environments.

High disconnection capacity
The disconnection capacity of the 10x38mm Ceramic Fuse varies according to different models. The standard disconnection capacity is 10kA (250V AC or 32V DC), and the high-performance model has a disconnection capacity of more than 50kA, which is suitable for high fault current scenarios in the industrial and energy fields. The design of the internal filling of quartz sand and the ceramic shell structure ensures that the fuse can still be safely disconnected even in extremely high current faults, avoiding damage to electrical equipment or fire risks, and improving the overall safety and stability of the system.

Precise fusing characteristics
The fuse design ensures that it can work continuously for 4 hours at 110% of the rated current to avoid frequent false disconnection; the longest disconnection time is 1 hour at 135% load, and it can be quickly disconnected within 120 seconds at 200%. This time-current characteristic is based on a precisely customized silver or copper alloy fuse to ensure rapid melting in the event of overcurrent or short circuit, reduce heat damage to electrical components, protect equipment while avoiding unnecessary downtime, and ensure the continuity and safety of system operation.

Compatible with multi-industry and multi-scenario applications
The standard ceramic fuse with a size of 10x38mm complies with international standards such as IEC 60127-2/4, UL 248, DIN 43653 and GB 9364 to ensure the uniformity of size, electrical performance and safety requirements. It is widely used in industrial equipment, high-power audio, transportation, battery management system (BMS), solar inverters and other fields. The standard structure facilitates rapid replacement and maintenance, improves system maintenance efficiency, reduces operation and maintenance costs, and meets the protection needs of diversified industrial and civil electrical equipment.
