Bussmann FNQ-R4 Class CC Time Delay Fuse 4 Amp 600V

The Bussmann FNQ-R4 is a Class CC time delay fuse rated for 4 amps at 600 volts AC. This midget fuse provides reliable overcurrent protection with a time delay characteristic that allows temporary harmless overloads while protecting against short circuits and sustained overcurrents.

Key Features:

• Class CC rated for superior current-limiting performance up to 200,000 amps interrupting capacity
• Time delay design prevents nuisance tripping from motor starting currents and other temporary surges
• Compact 13/32" x 1-1/2" midget fuse dimensions for space-saving installations
• 600V AC rated for commercial and industrial electrical systems
• Rejection-style design ensures proper fuse rating cannot be exceeded
• UL Listed and meets CSA standards for safety and reliability

Class CC fuses are ideal for protecting motor control circuits, lighting panels, and other critical electrical equipment where both time delay and high interrupting capacity are required. The rejection feature prevents replacement with lower-rated fuses, ensuring continued system protection.
