Eaton Bussmann Series UL Class CF, FCF 1RN Fuse

About Eaton Bussmann Series UL Class CF, FCF 1RN Fuse

Eaton Bussmann Series UL Class CF, FCF 1RN Fuse, fast-acting, single-element cube fuse, 1 A, non-idicating fuse, interrupting rating of 50 kA at 600 Vdc and 300 kA at 600 Vac

FCF 1RN Fuse, this fast-acting, single-element cube fuse, its specifications and features can be summarized as follows:

Basic Specifications

• Model: FCF 1RN
• Type: Fast-acting, single-element cube fuse
• Rated current: 1 A
• Indication type: Non-indicating
• Interrupting rating: 50 kA at 600 Vdc / 300 kA at 600 Vac

Main Features

1. Space saving:

• As part of the Bussmann series, this fuse has a compact design and is similar to other Class Compared with CC, J or RK fuses, it can save up to 70% space (when used in conjunction with a unique fuse holder or a UL 98 certified compact circuit protection switch).

2. High breaking capacity:

• With a breaking capacity of up to 300 kA, it can support higher equipment short-circuit current ratings (SCCR) to ensure effective protection of circuits in short-circuit conditions.

3. Safety:

• Compliant with IEC 60529 standard, it provides a touch-proof live design to help improve workplace safety.
• As a non-indicating fuse, its design also considers reducing the risk of accidental contact with live parts.

4. Applicability:

• 
  Suitable for applications requiring high surge load protection because it uses separate overload and short-circuit protection fuses and has a time delay function.
• Combined with the current limiting function of Class J fuses, it can limit short-circuit current and reduce damage to equipment and circuits.

5. Selectivity ratio:

• The selectivity ratio is 2:1 (for Low-Peak fuse series), which helps prevent electrical circuit interruption from extending to lines other than the fault circuit, improving system stability and reliability.

Application Scenarios

This fuse is widely used in various occasions that require precise control and protection of circuits, such as industrial control systems, power systems, transportation systems, and data centers. Its fast action and high breaking capacity enable it to quickly cut off the circuit in the event of a short circuit or overload, protecting equipment and personnel.
