BUSSMANN FRS-R-60 Fuse, 60 A, Dual, Non Indicating, Standard, 250 V

Bussmann FRS-R-60 fuse is used in power distribution plants, HVAC systems and data centres to provide overcurrent protection.

Working Mechanism:

• When an excessive current flows through the circuit, the heat generated causes the heat-sensitive element to melt.
• This melting process is intentionally delayed due to the fuse's time-delay feature, allowing temporary overcurrent conditions that might occur during motor starting or other transient events.
• Once the heat-sensitive element melts, the circuit is interrupted, preventing further flow of excessive current and protecting the circuit and equipment from damage.

Features:

• It features fibreglass construction, ensuring durability and corrosion resistance.
• This Class RK5 fuse features a cylindrical body style, contributing to its compact and standardised form.
• It is designed to fit into fuse block styles that incorporate the rejection feature, ensuring secure & proper installation.
• This dual-element fuse has an interrupt rating of 200kAIC at 600VAC for high alternating current fault currents and 20kAIC at 250VDC for significant direct current fault currents.
• It is designed with a ferrule end on both sides, allowing for a secure and reliable connection.

Frequently Asked Questions:

Q. What is the purpose of the time-delay feature in Bussmann FRS-R-60 fuse?

A. The time-delay feature in the fuse allows it to withstand short-duration overcurrents that might occur during motor starting or other initial power surges.

Q. What is the purpose of the dual element design in this fuse?

A. The dual-element design enhances the fuse's capability to handle different types of overcurrent conditions effectively, improving its overall performance and reliability.

Q. What does the Class RK5 mean for this fuse?

A. The Class RK5 indicates that the fuse has a time-delay characteristic, allowing it to tolerate short-duration overcurrent conditions during startup or inrush currents.

Q. What is the response time of Bussmann FRS-R-60 fuse?

A. It has a response time of 10 seconds at 500%.
