5x20 mm cylindrical fuse links

Cylindrical fuse inserts 5x20 mm - a key element of circuit protection

Cylindrical fuse inserts 5x20 mm are irreplaceable safety elements in electrical installations.   They protect devices against the effects of short circuits and overloads. Their compact dimensions facilitate installation in various applications. At Onninen we offer a wide selection of these products from renowned manufacturers.

Our portfolio includes inserts with various electrical parameters. Models are available with rated currents from 0.5A to 8A. The rated voltage is standard 250VAC. These inserts are suitable for many applications. They are often used in measuring and control devices.

Types of cylindrical fuse inserts 5x20 mm

Our offer includes various types of 5x20 mm fuse inserts:

• Fast inserts (F) - for semiconductor protection
• Delayed fuses (T) - for circuits with starting currents
• Very fast (FF) inserts - for sensitive electronic systems
• Medium delay inserts (M) - universal use

Selecting the right type of insert is crucial for effective circuit protection.   Our consultants will be happy to help you choose the best solution. Our experience shows that fast fuses work best in circuits with semiconductor elements. We recommend slow fuses for protecting motors and transformers.

Selection criteria for cylindrical fuse links 5x20 mm

When selecting 5x20 mm fuse links, several key parameters should be taken into account:

• Rated current - matched to the circuit load
• Time-current characteristic - depending on the protected device
• Breaking capacity - adequate to expected short-circuit currents
• Nominal voltage - according to the installation voltage
• Operating temperature - appropriate to environmental conditions

Proper selection of these parameters ensures effective protection and reliable operation of the security system.   At Onninen we offer inserts with different characteristics. This allows us to adapt the product to the specific requirements of the customer. Our specialists will be happy to advise on the selection of the optimal solution.

Many customers ask us about the differences between glass and ceramic inserts. Glass inserts allow for a visual assessment of the fuse condition. Ceramic inserts, on the other hand, have a higher breaking capacity. We offer both types of products. The selection depends on the specific application and user preferences.
