Basic Info
Model No.: RF2-20(H)
Product Description
Model NO.: RF2-20(H) Type: Current Fuse Shape: Insert Fusing Device: Pop-up Solid Trademark: songshan Origin: Shanghai, China Breaking Capacity: High Usaga: Low Voltage Fusing Speed: F Standard: VDE Specification: 5x20 mm HS Code: 85361000 RF2-20(H) series
RF2-20 (H) ceramic tube fast-acting high breaking capacity fuse with lead, size: Ф5×20±1, the products conform to IEC60127-11 standard.
This product is a high breaking product, the melt of such fuse with high breaking capacity is usually made of copper, and also silver. When the rated current is smaller, the melt is usually made into a filament; when the rated current is larger, it will be made into a variable cross-section. Since copper and silver are metal materials with high melting point, to break current reliably under high overload current, low melting point metal is often welded in the melt intervals, such as tin or cadmium alloy, in order to reduce the melting temperature, this effect is also known as metallurgical effect (M effect).
