RS PRO 500mA T Ceramic Cartridge Fuse 250V, Slow Blow, 5.2 x 20 mm, Anti-Surge 563-659

The RS PRO 500mA T Ceramic Cartridge Fuse, model 563-659, is designed for dependable protection of electrical and electronic circuits against overcurrent and damaging surges. This fuse is engineered with a slow-blow (T) characteristic, allowing it to tolerate temporary current spikes without rupturing, making it highly suitable for applications where motors or appliances require an initial surge when switching on.

With a rated current of 500mA and maximum voltage handling of 250V AC, this fuse is compatible with a wide range of board and panel protection circuits. Its anti-surge (HBC - High Breaking Capacity) design ensures safety when installed in environments with potential high fault currents, preventing catastrophic failure.

The body is constructed from robust ceramic material, providing excellent thermal and electrical insulation as well as resistance to heat and mechanical stress. The 5.2 x 20 mm cartridge size is an industry standard, facilitating easy replacement and fitment in compatible fuse holders. The fuse's minimum operating temperature is -55°C, while it can function up to 125°C, supporting operation in demanding conditions.

Time-delay characteristics mean this fuse will disconnect circuits only after a sustained overload, offering superior protection to sensitive electronics and devices subject to occasional power surges. Application category gRL makes it suitable for both general and motor load circuits.

Typical use cases include protecting motors, air conditioners, refrigerators, pumps, and other appliances in industrial, commercial, residential, and automotive environments. Its compliance with RoHS, UL, VDE, and CSA standards guarantees dependable performance and broad acceptance in regulated installations.

Thanks to the anti-surge capability, the RS PRO fuse prevents unnecessary downtime caused by premature fuse failures, ensuring continuity of operation and reducing maintenance needs. Board and panel manufacturers, appliance engineers, and system integrators trust this solution for its reliable circuit isolation and overcurrent protection.
