FLSR015-ID - 15Amp Fuse

FLSR015-ID - 15Amp Fuse

The FLSR015-ID is a 15-amp Class RK5 time-delay fuse designed for your industrial and commercial electrical applications where dependable overload and short-circuit protection is critical. Rated for 600VAC and 300VDC, this dual-element cartridge fuse can handle normal, temporary inrush currents while still responding when an overload or fault condition requires the circuit to be interrupted. One particularly useful feature is its built-in blown-fuse indicator.

Key Features and Benefits

• 15-amp rating for compatible industrial and commercial circuits.
• A 600 VAC maximum voltage rating provides flexibility across many common electrical applications.
• Rated for operation at up to 300VDC.
• Class RK5 dual-element construction provides both overload and short-circuit protection.
• Time-delay operation allows normal temporary inrush currents without unnecessarily opening the circuit.
• Indicating design makes a blown fuse easier to identify during inspection and troubleshooting.
• Current-limiting performance helps limit damaging fault current during a short circuit.
• 200kA RMS symmetrical AC interrupting rating at 600VAC.

Where It Works Best

The FLSR015-ID 15A fuse makes sense in applications where temporary current surges are common, but reliable circuit protection remains essential. Motor circuits are a good example: startup can produce an inrush of current that shouldn't necessarily cause the fuse to open. The time-delay characteristic helps accommodate those brief conditions while maintaining protection against sustained overloads and short circuits.

Common applications for the FLSR_ID series include motor branch circuits, motor control centers, transformers, switchboard mains and feeders, service entrance switches, and general-purpose circuits. The visual indicator is especially handy in equipment with multiple fuses, where quickly finding the one that has opened can mean less time spent troubleshooting and less downtime.
