6 × 30MM Fast (Blow) Fuse 250V with Ceramic, Glass and Leads

There are several key dimensions that need to be sorted out for (3AB/3AG) 6 X 30, 6.3 X 32 säkringar: Första, the basic specifications, the size is 6mm in diameter and 30mm in length (the standard name is 6x30mm). There are two types of packaging materials: glass and ceramic. The current range is very wide, covering from 0.1A to 30A, and the voltage is mainly 250V.

Regarding the type characteristics, the difference between fast-acting type (F type) and slow-acting type (T type) is very important. This is similar to the 5*20 säkring, but the application scenario may be different. In terms of certification, it is particularly noted that the CCC mandatory certification range is 500mA-30A current segment, which is critical for compliant procurement.

In terms of application scenarios, 10A-30A models are commonly used on industrial equipment. The waterproof fuse holder (IP67) is suitable for vehicle and outdoor use. Accessory information is also very practical, such as the R3 series fuse holder supports 30A current, and there are waterproof models with leads.

Procurement recommendations need to highlight certification requirements (UL/CCC)6 and current calculation rules (1.5 times the working current). The price range varies greatly, ranging from a wholesale price of $0.01 per piece to a retail price of $0.03 per piece.

The following is a detailed technical analysis and application guide for ‌6×30, 6.3 x 32 fuses‌. Based on the latest industry standards and market product information:

🔧 1. Core specifications and types
‌Size and structure‌
‌Standard size‌: 6mm diameter × 30mm length, cylindrical design, with metal cap electrodes at both ends. ‌
‌Packaging material‌:
‌Glass tube‌: Transparent and visible, easy to quickly detect the fuse status (common current ≤10A). ‌
‌Ceramic tube‌: High temperature resistant, explosion-proof, suitable for industrial high current scenarios (nuvarande>10A). ‌

‌Electrical parameters‌
‌Rated voltage‌: Mainstream 250V, some models support 125V. ‌
‌Current range‌:
‌Small current type‌ (0.1A–6.3A): used for precision circuits, LED lighting. ‌
‌Medium and high current type‌ (10A–30A): suitable for motors and power modules. ‌

‌Classification of fuse characteristics‌
‌Fast-break type (F type): millisecond response, protecting sensitive electronic equipment (such as marked F15A). ‌

‌Slow-break type (T type): resistant to instantaneous impact, suitable for motors and transformers (such as marked T10A). ‌

⚡ 2. Key performance and certification ‌Safety performance‌
‌Breaking capacity‌: up to 200A@250V (ceramic tube model), ensuring safe disconnection in case of short circuit. ‌
‌Temperature adaptability‌: operating temperature -55℃~125℃, passed -40℃~90℃ hot and cold cycle test. ‌

‌Mandatory certification requirements‌
‌CCC certification‌: models with current 500mA–6.3A are mandatory requirements for domestic market access. ‌
‌International certification‌: UL, VDE, and RoHS certifications are essential for export and industrial scenarios. ‌

🛠️ 3. Application scenarios and accessories
‌Typical application areas‌
‌Industrial equipment‌: servo drive, power module (10A-30A ceramic fuse). ‌
‌Car and outdoor‌: waterproof fuse holder (IP67 grade) for street lights, car inverters. ‌
‌Household appliances‌: audio equipment, emergency power supply (commonly used 1A-5A glass tube). ‌

‌Matching fuse holder‌
‌PCB installation type‌: such as R3-67 series, supports 30A current, tinned copper terminals. ‌
‌Lead waterproof type‌: with PVC sheath, suitable for humid environments (such as H3-520E). ‌

💡 4. Selection and purchasing guide
‌Selection principle‌
‌Current matching‌: select according to the maximum operating current of the circuit × 1.5 gånger (till exempel: 4A circuit selects 6A fuse). ‌
‌Type selection‌:
Digital circuit/vehicle equipment → Fast-break type preferred (F)
Motor/transformer → Slow-break type required (T) ‌
‌Purchasing channels and costs ‌
‌Bulk purchase‌: Alibaba (Yaxun Electronics) ($0.02/piece, 1,000 pieces minimum). ‌
‌Retail replacement‌: (Yaxun Electronics) JD.com/Tmall (10 pieces per pack, about $0.06/piece, such as the Litte brand). ‌

‌Suggestions for avoiding pitfalls‌
Reject uncertified products, especially confirm the CCC mark (mandatory when the current is ≤6.3A). ‌
For industrial scenarios, ceramic tube + UL certification combination (such as Litte and Bussmann brands) is preferred. ‌

💎 Summary
6×30 fuses are core protection components for industrial and high-power equipment. Three points must be strictly followed when selecting them:
‌Matching of current and fusing characteristics‌ (F/T type);
‌Certification compliance‌ (CCC/UL/VDE/CE mandatory range);
‌Environmental adaptation‌ (keramisk + waterproof seat for industry, glass tube for home use).
Ceramic tube models (such as Bussmann MDL series) are significantly safer than glass tubes in 30A high current scenarios.
