2.5 Amp 600 Volt Class CC Time Delay · Littelfuse CCMR02.5

What this product is for

The Littelfuse CCMR02.5 is a Class CC dual-element time-delay fuse for overcurrent protection in commercial and industrial control panels, branch circuits, lighting circuits, and certain motor applications. It is a 2.5A fuse with a 600VAC rating and 300VDC rating.

Use for

Use for Class CC fuseholders, compact branch circuit protection, lighting circuits with inrush, and motor circuits where a time-delay fuse is specified. This series is commonly selected when panel space is limited and high interrupting capacity is required.

Avoid for

Avoid for applications that require a different fuse class, a different ampere rating, or a fast-acting fuse. Do not substitute without confirming voltage, available fault current, holder compatibility, and equipment protection requirements.

Best for

Best for electricians and maintenance teams needing a compact Class CC fuse for nuisance-resistant protection on loads with temporary startup or inrush current. Typical buying factors are 2.5A rating, time-delay opening, and Class CC footprint.

Installed in

Installed in fuse blocks, clips, or holders designed for Class CC fuses, including control panels, machinery, HVAC equipment, and lighting distribution assemblies in commercial and industrial facilities.

Why this product exists

This fuse provides compact branch circuit protection with time-delay performance so normal temporary inrush is less likely to cause nuisance opening. As typical guidance, time-delay fuses are commonly used on motor and lighting loads where startup current is higher than running current. Actual performance depends on equipment characteristics, available fault current, and local electrical code.

Compared with similar products

Compared with fast-acting Class CC fuses, the CCMR series is intended for applications that benefit from time-delay characteristics. Compared with larger fuse classes, Class CC helps save panel space while still providing high interrupting capacity.
