FLNR070 - 70 Amp Fuse

FLNR070 - 70 Amp Fuse

The FLNR070 is a 70-amp, 250V Class RK5 time-delay fuse made for your electrical applications where temporary current surges are part of normal operation. Instead of reacting immediately to a brief inrush, its dual-element, Slo-Blo design provides a time delay before opening, helping prevent unnecessary fuse operation while still providing overcurrent protection.

Key Features and Benefits

• 70 amp rating: Designed for circuits and equipment specifying a 70A fuse.
• Time-delay performance: The Slo-Blo/time-lag characteristic accommodates brief current surges without opening as quickly as a fast-acting fuse.
• Dual-element design: Combines time-delay operation with protection against sustained overcurrent conditions.
• 250 VAC / 125 VDC ratings: Gives the FLNR070 flexibility across compatible AC and DC applications.
• Class RK5 fuse: Makes it easy to identify the proper fuse class when matching an existing electrical system or equipment specification.
• Knife-blade construction: Designed for installation in the appropriate fuse block, clip, or holder.

Where It Works Best

The FLNR070 makes the most sense in compatible commercial and industrial electrical applications where short periods of elevated current can occur during normal operation. Its time-delay characteristic allows it to handle temporary inrush conditions without behaving like a fast-acting fuse, which can be especially useful when the connected equipment naturally draws more current for a short period.
