CCMR fuses are one of the most versatile and economical fuse products available in the market. They are commonly used in circuit protection, power distribution, and control applications. CCMR fuses have the following advantages:

1. Lowest melting I2t of all industry-standard, Class CC fuses.
2. Time-delay characteristics compatible with motor starting protection requirements.
3. Compact design with the same physical size as a Class L fuse.
4. Certified for use in UL listed motor controllers.
5. Superior temperature cycling capability.
6. Low gap voltage drop for precise protection of modern sensitive electronic equipment.
7. Rated in accordance with UL Standard 248-14.

CCMR fuses provide overcurrent protection to motors, transformers, electronic and other sensitive equipment. With up to 500 amperes of continuous current and up to 400 V, these fuses can be used to protect both 50 Hz and 60 Hz applications in a variety of industrial, commercial, and residential environments. The 500 A fuses also provide protection of important line side devices in high voltage switchgear and other power utility equipment. The gap voltage of CCMR fuses is also designed to provide optimal protection for modern electronic equipment.

The working principle of CCMR fuses is relatively simple. When a current spike higher than the rated current of the fuse passes through the fuse, the fuse heats up, melts, and breaks the circuit. This interrupts the flow of current and prevents overload or short circuit current from damaging connected components. The time-delay feature of CCMR fuses prevents the fuse from tripping prematurely due to inrush current during motor starts or other temporary spikes. This time delay also prevents nuisance trips when line voltage drops or other system problems occur.

The construction of CCMR fuses consists of a housing, fuse element, and fuse link. The fuse housing is made of a impact-resistant thermoplastic material and serves to contain the two fuse elements. The fuse element is the active part of the fuse and is made of a metal alloy that melts when exposed to excessive currents. The fuse link is a short piece of metal strip that connects the two elements. When the current surpasses the rated value of the fuse element, the element melts and the fuse link breaks, which interrupts current flow.

CCMR fuses are a great choice for use in a wide variety of applications. They are reliable and cost-effective and have become an industry standard for circuit protection. Their compact size and low gap voltage drop make them a great choice for protecting modern electronics. With their low I2t characteristics, they also make a great choice for motor circuit protection.
