FRS-R-12 TIME DELAY FUSE

Description

The FRS-R-12 Fuse is a Class RK5 dual-element time-delay fuse designed for motor protection and general industrial power distribution. It allows short overloads (like motor starting current) without blowing, but quickly interrupts dangerous fault currents to protect equipment and wiring.

It is commonly used in motor control centers, transformers, panelboards, and industrial machinery.

Key Features

• Time-delay (slow-blow) dual-element fuse
• Allows motor starting inrush current without nuisance blowing
• High interrupting capacity for strong fault protection
• Current-limiting design reduces equipment damage during short circuits
• Suitable for AC and DC industrial systems
• Cylindrical cartridge with ferrule ends
• Reliable protection for motors and transformers
• Class RK5 industrial standard fuse
• High safety and long service life
• Widely used in industrial control panels
