Cylindrical Cartridge Fuses Selection Guide: Technical Criteria & Application Standards
Cylindrical Cartridge Fuses selection guide: technical parameters, mounting and compliance standards, and Schneider Electric, TP Elektrik comparison.
A cylindrical cartridge fuse is a fusible fuse link with a cylindrical body and metal caps at both ends, made in standard sizes such as 10x38 and 14x51 mm. Fitted into fuse holders and fused disconnectors, it protects control circuits, small motor outputs and photovoltaic array lines. The Schneider Electric DF2 series lists fuse links in sizes 8x31, 10x38 and 14x51 with values such as 6 A, 10 A, 16 A, 20 A, 25 A and 40 A, the ABB E 9F PV series lists DC cartridge fuses for solar arrays, and TP Elektrik 10x38 fuses are also listed. Choose the cartridge fuse first by the body size that fits the holder, then by rated current, AC or DC rated voltage and duty class (gG for general purpose, aM for motor circuits, gPV for photovoltaic). A cartridge made for AC circuits is not a substitute for a gPV fuse on a DC photovoltaic line, even if the size is the same; photovoltaic fuses fall under IEC 60269-6. The Cylindrical Cartridge Fuses category on Welibaba includes 21 active models from leading manufacturers such as Schneider Electric, TP Elektrik.
Key Technical Parameters for Selecting Cylindrical Cartridge Fuses
To specify the right Cylindrical Cartridge Fuses model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Fuse Size | 10 x 38 mm, 14 x 51 mm, 22 x 58 mm, 8 | Verify against project schedule and load calculation |
| Series | TeSys sigorta bağlantı kesici | Verify against project schedule and load calculation |
| Rated Current (In) | 10 A 400 V, 10 A 500 V, 100 A 500 V, 16 A 400 V | Verify against project schedule and load calculation |
| Fuse Type | NFC | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Fuses.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as Miniature Circuit Breakers with Residual Current Protection, Medium Voltage Fuses, Blade Fuses.
