FLSR17.5-ID - 17½ Amp Fuse

FLSR17.5-ID - 17½ Amp Fuse

Looking for the right 17.5A Class RK5 fuse and don't want to second-guess the specifications? The FLSR17.5-ID brings together the details that matter: a 17.5-amp rating, 600V AC capacity, time-delay operation, dual-element construction, and an indicating design. Add its Class RK5 rating, industrial cartridge construction, and 300V DC capability, and you have a very specific fuse for applications that call for this exact combination of electrical and physical characteristics.

Key Features and Benefits

• 17.5A rating: Need the less-common 17-1/2 amp size? That's exactly what the FLSR17.5-ID provides.
• 600V AC capability: Suitable for compatible AC applications requiring a fuse rated up to 600 volts.
• 300V DC rating: Can also be used in properly specified DC applications within its stated ratings.
• Time-delay operation: The Slo-Blo / Time Lag characteristic helps the fuse ride through appropriate temporary inrush current rather than opening prematurely.
• Dual-element construction: Gives the fuse its time-delay operating characteristics while providing overcurrent protection.
• Indicating design: Helps make fuse-status identification easier during inspection and troubleshooting.
• Class RK5 configuration: An important specification when matching a replacement fuse to existing equipment.
• Industrial cartridge style: Made for compatible fuse blocks, clips, and holders.

Material Compliance and Certifications

The available product information identifies the FLSR17.5-ID as a Class RK5 fuse. However, the supplied specifications do not provide sufficient information to specify exact certification listings or material compliance declarations for this particular catalog number.

Where It Works Best

The FLSR17.5-ID is a good fit when the equipment specifically calls for a 17.5A, Class RK5 time-delay fuse and normal operation can involve brief current surges. That's where the time-delay characteristic earns its keep. Rather than opening simply because current rises momentarily during an acceptable inrush condition, the fuse is built to tolerate appropriate short-duration surges while still providing overcurrent protection.
