Littelfuse KLDR003.HXP Class Cc Time-delay Fuse 3A 600V

Product Description

The LITTELFUSE KLDR003.HXP is a Class CC time-delay fuse rated at 3 amps and 600 volts. Class CC fuses are compact, current-limiting devices designed to provide reliable overcurrent protection in control circuits, motor branch circuits, and general-purpose electrical applications. The time-delay characteristic allows the fuse to tolerate brief inrush currents without nuisance opening, while still responding quickly to sustained overloads and short-circuit conditions. Licensed electricians and industrial maintenance technicians typically install this fuse in fuse blocks and disconnect switches sized for the Class CC form factor.

The KLDR003.HXP is suited for use in residential, commercial, and light industrial electrical systems where Class CC fuse holders are specified. Typical applications include motor control centers, control panel branch circuit protection, transformer primary protection, and HVAC equipment control circuit protection. Its compact Class CC body fits standard 13/32-inch by 1-1/2-inch fuse holders commonly found in control panels and equipment disconnects.

Key Features

• 3-amp rating with time-delay action for tolerance of motor inrush and transformer magnetizing currents
• 600-volt rating suitable for single-phase and three-phase branch circuit applications
• Class CC form factor provides rejection feature that prevents substitution of lower-interrupting-capacity fuse types
• Current-limiting design reduces arc flash energy and protects downstream components during fault conditions
• Compact body fits 13/32-inch by 1-1/2-inch Class CC fuse holders

Compatibility

Designed as a Class CC fuse replacement for fuse holders and disconnect switches accepting the 13/32-inch by 1-1/2-inch Class CC rejection-style body.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before removing or installing fuses. Use an appropriately rated fuse puller when servicing energized adjacent circuits. Verify that the fuse holder is rated for at least 600 volts and 3 amps before installation.
