RS PRO 630mA Fast Acting Ceramic Cartridge Fuse 5 x 20 mm 250V AC 563-378

RS PRO 630mA Fast Acting Ceramic Cartridge Fuse model 563-378 is a high-quality miniature fuse designed to protect electrical devices and internal circuits from short circuits and overcurrent conditions. This quick-acting fuse is manufactured with a ceramic body, providing excellent mechanical strength and high breaking capacity, making it reliable for multiple industrial and commercial applications.

The fuse has a standard cartridge size of 5 x 20 mm with a diameter of 5 mm and overall length of 20 mm, making it compatible with common fuse holders in electrical panels and devices. It operates safely at voltages up to 250V AC and maintains function across a wide temperature range from -55°C to 125°C.

Fast acting (F speed rating) design ensures that the fuse responds quickly to overcurrent spikes, protecting sensitive electronic components such as thyristors, diodes, and triacs. As a High Breaking Capacity (HBC) fuse, it can safely interrupt fault currents without excessive damage.

This fuse is suitable for protecting various household and industrial equipment including motors, air conditioners, refrigerators, and pumps. It is widely applied in industrial, commercial, and residential electrical systems to ensure safety and circuit integrity. Once the fuse blows due to fault current, replacement is necessary to restore protection.

This ceramic cartridge fuse has a fast-acting characteristic suited for general purpose circuit protection. High reliability ensured by compliance with CSA, RoHS, UL, and VDE certifications. Compact cylindrical form with standard 5 x 20 mm dimensions for easy replacement and compatibility.

Designed for safe operation under varied thermal conditions and mechanical stresses. Package includes a single fuse suitable for individual circuit protection requirements. Explore more from RS PRO’s range of Cartridge Fuses on EnvMart for all your electrical circuit protection needs.
