FRN-R-8/10 Description

Short technical summary and product information.

The FRN-R-8/10 is an RK5 class, slow-blow cartridge fuse manufactured by Eaton - Bussmann Electrical Division. It is rated for 8 mA continuous current at 250 VAC and 125 VDC, with a high interrupting capacity of 200 kA AC and 20 kA DC. The fuse features a slow blow response time, making it suitable for applications with inrush currents or transient surges.

 

The fuse measures 0.560 inches in diameter and 2.000 inches in length (14.22 mm x 50.80 mm), and is designed for use with a fuse holder (requires holder mounting type). It is housed in a cartridge, non-standard package and carries approvals from CE, CSA, and UL, confirming its quality and safety for industrial use.

 

Typical applications include electrical and industrial circuit protection, such as branch circuits, motor starters, and transformer protection. The RK5 class provides time-delay characteristics and high fault current interruption capability, making the FRN-R-8/10 a reliable overcurrent protection component for demanding environments.
