Bussmann FRS-R Time Delay Fuse 5A Class RK5 Dual Element Ferrule End

Bussmann FRS-R Time Delay Fuse 5A Class RK5 Dual Element Ferrule End

Professional Time Delay Protection for Motor and Inductive Load Applications

The Bussmann FRS-R series time delay fuse delivers reliable overcurrent protection with dual element design for motor circuits and inductive loads. This 5A Class RK5 fuse features ferrule end connections for secure installation and provides 10 second time delay at 500% overload, allowing temporary inrush currents while protecting against sustained overcurrent conditions. With 200 kAIC interrupt rating at 600 Vac and CE marking compliance, this non-indicating fuse ensures dependable circuit protection in commercial and industrial applications.

Professional Features & Benefits

• 5A Current Rating: Precisely calibrated amperage protection for motor and lighting circuits requiring time delay characteristics.
• Class RK5 Design: Current-limiting performance reduces let-through energy and provides superior short-circuit protection compared to standard fuses.
• Dual Element Construction: Time delay element handles motor starting currents while fast-acting element provides short-circuit protection.
• Ferrule End Connections: Secure mechanical and electrical connection in fuse holders and disconnect switches.
• 200 kAIC Interrupt Rating: High fault current interruption capability at 600 Vac ensures reliable protection in demanding electrical systems.
• 10 Second Time Delay: Allows temporary 500% overload conditions typical of motor starting while protecting against sustained overcurrent.
• CE Marked Compliance: Meets European conformity standards for international installation requirements.
