玻璃保險絲:
常見尺寸與外觀

5x20 mm：直徑約 5mm、長度 20mm（市面上最常見的標準規格）。

6x30 mm (3AG)：直徑約 6mm、長度 30mm（較大型電器或舊式設備常用）。

其他微型尺寸：如 3.6x10mm 等特殊規格。 [1, 2, 3]

電氣與熔斷規格

額定電壓：多數標示為 250V（可相容 110V 或 220V 電路）。

額定電流：常見範圍從 0.1A 到 15A 或 30A 不等（如 0.5A、1A、2A、3A、5A、10A、15A）。 [1, 2]

熔斷特性：
- 快斷型（Fast-Acting / F）：管內通常是一條直線金屬絲，電流過載時瞬間熔斷。
- 慢斷型（Slow-Blow / Time Lag）：管內金屬絲有繞圈或附帶錫球，能承受馬達或變壓器開機時的短暫突波電流

Glass Fuses:

Common Sizes and Appearances
5x20 mm: Approximately 5mm in diameter and 20mm in length (the most common standard size on the market).
6x30 mm (3AG): Approximately 6mm in diameter and 30mm in length (commonly used in larger appliances or older equipment).
Other Miniature Sizes: Such as 3.6x10mm and other special sizes. [1, 2, 3] Electrical and Fuse Specifications
Rated Voltage: Mostly marked as 250V (compatible with 110V or 220V circuits). [1]
Rated Current: Common ranges from 0.1A to 15A or 30A (e.g., 0.5A, 1A, 2A, 3A, 5A, 10A, 15A). [1, 2]
Fuse Characteristics:
Fast-Acting (F): Usually a straight metal wire inside the tube, which melts instantly when the current is overloaded. Slow-Blow/Time Lag type: The metal wire inside the tube is coiled or has solder balls attached, which can withstand the brief surge current when the motor or transformer is started.
