SCHURTER 7030.3280 Equivalent & Substitute Parts

Part Overview

The SCHURTER 7030.3280 is a 500 mA glass cartridge fuse rated for 220 V AC and 125 V DC operation in a 5mm x 20mm form factor. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs. The slow-blow response characteristic and 60A AC / 4kA DC breaking capacity define its application scope in circuit protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7030.3280 is determined by the following critical parameters:

• Current Rating: 500 mA (exact match required)
• Package / Case: 5mm x 20mm (mechanical compatibility with existing holders)
• Response Time: Slow Blow (functional characteristic for inrush current tolerance)
• Voltage Rating - AC: Minimum 220 V (equal or higher acceptable)
• Voltage Rating - DC: Minimum 125 V (equal or higher acceptable)
• Fuse Type: Cartridge format (interchangeable with glass or ceramic construction)
• Mounting Type: Requires Holder (standard cartridge holder compatibility)

The SCHURTER 0001.2501 meets all substitution criteria with enhanced voltage ratings and active product status.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 0001.2501 is the direct substitute for the 7030.3280. Both components share identical current ratings, response characteristics, and mechanical form factors. The 0001.2501 provides superior voltage ratings (250 V AC / 300 V DC versus 220 V AC / 125 V DC), expanded operating temperature range (-55°C ~ 125°C versus -40°C ~ 70°C), and active product status ensuring continued availability.

The ceramic construction of the 0001.2501 differs from the glass construction of the 7030.3280 but maintains equivalent electrical performance within the 5mm x 20mm cartridge holder interface. The 0001.2501 carries dual certifications (cURus, VDE) compared to the single UR certification of the main part, providing broader regulatory acceptance.

Breaking capacity differs between the parts (1.5kA for 0001.2501 versus 60A AC / 4kA DC for 7030.3280). Applications requiring the higher breaking capacity of the original part require evaluation of alternative solutions outside this substitute group.

Frequently Asked Questions (FAQ)

Q: Can the 0001.2501 be used as a direct replacement in existing 5mm x 20mm fuse holders?

A: Yes. Both the 7030.3280 and 0001.2501 are cartridge fuses with 5mm x 20mm dimensions designed for standard cartridge holders. Mechanical compatibility is confirmed.

Q: What is the difference between glass and ceramic fuse construction?

A: Glass and ceramic are both acceptable cartridge fuse materials. The 0001.2501 ceramic construction provides equivalent electrical performance and protection characteristics as the 7030.3280 glass construction within the specified parameters.

Q: Are the voltage ratings interchangeable?

A: The 0001.2501 has higher voltage ratings (250 V AC / 300 V DC) than the 7030.3280 (220 V AC / 125 V DC). Higher-rated components are acceptable for circuits designed for lower voltages. Confirm circuit voltage requirements do not exceed 250 V AC or 300 V DC.

Q: Why does the breaking capacity differ between the parts?

A: Breaking capacity is a distinct electrical characteristic. The 0001.2501 breaking capacity of 1.5kA is lower than the 7030.3280 (60A AC / 4kA DC). Applications requiring the original breaking capacity specification must evaluate alternative solutions.

Q: What certifications apply to the substitute part?

A: The 0001.2501 holds cURus and VDE certifications. The 7030.3280 holds UR certification. Confirm circuit design requirements against applicable regulatory standards for your application.

Q: Is the 0001.2501 currently available?

A: Yes. The 0001.2501 is classified as active product status with 897 pieces in stock, ensuring supply continuity compared to the obsolete 7030.3280.
