6× 30 mm rychle (Pomalý) Trubice pojistky s keramikou, Sklo

There are several key dimensions that need to be sorted out for (3AB/3AG) 6 * 30, 6.3 * 32 mm pojistky: První, 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, Rozdíl mezi rychle působícím typem (F typ) a pomalu působící typ (T typ) je velmi důležité. To je podobné jako 5*20 pojistka, Scénář aplikace však může být odlišný. Z hlediska certifikace, it is particularly noted that the CCC mandatory certification range is 500mA-30A current segment, což je rozhodující pro kompatibilní zakázku.

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.

6 X 30mm Electrical Fuses China Wholesale Distributor

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 za kus.

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:
Skleněná trubice: Transparent and visible, easy to quickly detect the fuse status (common current ≤10A). ‌
Keramická trubice: High temperature resistant, explosion-proof, suitable for industrial high current scenarios (proud>10A). ‌

‌Electrical parameters‌
Jmenovité napětí: Mainstream 250V, some models support 125V. ‌
Aktuální rozsah:
‌Small current type‌ (0.1A–6.3A): used for precision circuits, LED osvětlení. ‌
‌Medium and high current type‌ (10A–30A): suitable for motors and power modules. ‌

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

Typ s pomalým přerušením (T typ): resistant to instantaneous impact, vhodné pro motory a transformátory (such as marked T10A). ‌

⚡ 2. Key performance and certification ‌Safety performance‌
Vypínací schopnost: up to 200A@250V (ceramic tube model), zajištění bezpečného odpojení v případě zkratu. ‌
Adaptabilita na teplotu: 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
‌Industriální vybavení‌: servopohon, napájecí modul (10A-30A ceramic fuse). ‌
‌Car and outdoor‌: vodotěsný držák pojistky (Třída IP67) for street lights, car inverters. ‌
‌Household spotřebiče‌: audio equipment, emergency power supply (commonly used 1A-5A glass tube). ‌

‌Odpovídající držák pojistky‌
‌Typ instalace PCB‌: such as R3-67 series, supports 30A current, tinned copper terminals. ‌
‌Lead waterproof type‌: with PVC sheath, suitable for humid environments (jako je H3-520E). ‌

💡 4. Selection and purchasing guide
‌Selection principle‌
‌CURRENT SPORTY‌: select according to the maximum operating current of the circuit × 1.5 časy (například: 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 (Elektronika Yaxun) ($0.02/kus, 1,000 kusů minimum). ‌
‌Retail replacement‌: (Elektronika Yaxun) 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, keramická trubice + UL certification combination (such as Litte and Bussmann brands) is preferred. ‌

💎 Shrnutí
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 (keramický + 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.
