Cooper Bussmann LP-CC-4-1/2 Time Delay Cc Fuse 4.5A

Product Description

The COOPER BUSSMANN LP-CC-4-1/2 is a Class CC time delay cartridge fuse rated at 4.5 amps, designed for general-purpose overcurrent protection in industrial and commercial control circuits. The time delay characteristic allows momentary inrush currents to pass without nuisance opening, while still providing fast response to sustained overloads and short circuits. At 10.3 mm in diameter and 38.10 mm in overall length, this fuse fits standard CC-class fuse holders. It carries an interrupt rating of 200 kA at AC (RMS) and 20 kA at DC. Licensed electricians and control panel technicians typically install this fuse in motor control centers, HVAC control circuits, and power distribution panels.

The LP-CC-4-1/2 is suited for use in residential and light commercial HVAC systems, motor starters, solenoid valve circuits, and low-voltage transformer secondary protection where a Class CC fuse holder is present. Its dual-element construction distinguishes it from single-element fast-acting fuses, making it a reliable choice wherever temporary overloads are expected during startup. This fuse is sold individually but must be ordered in multiples of 10.

Key Features

• Class CC time delay cartridge fuse — 4.5 amp rating with dual-element construction
• High interrupt rating: 200 kA at AC (RMS) and 20 kA at DC
• Standard CC dimensions: 10.3 mm diameter, 38.10 mm overall length (1.5 inches)
• Mounts in standard CC-class fuse holders — no adapters required
• CE Certified, CSA Class 1422-02 File 53787 Certified, and UL Listed 248-4 Guide JDDZ File E4273
• Two-element design tolerates motor and transformer inrush without nuisance blowing

Compatibility

Designed as a direct-fit replacement for Class CC fuse holder applications requiring a 4.5 amp time delay cartridge fuse with standard 10.3 mm diameter and 38.10 mm length dimensions.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always de-energize and lockout/tagout the circuit before replacing any fuse. Confirm the fuse holder is rated for Class CC fuses and verify the circuit voltage and amperage do not exceed the fuse ratings. Do not substitute a fast-acting fuse where a time delay type is specified by the equipment manufacturer.
