Product Description
The RS PRO Glass Cartridge Fuse with model 563-621 is a high-quality protection device designed for safeguarding electronic circuits from overcurrents and short circuits. With a current rating of 3.15A and a voltage rating of 250V AC, this fuse is ideal for a broad spectrum of low-voltage electrical devices and installations.
Constructed with a durable glass body, the fuse measures 5 x 20 mm, a globally recognized standard that ensures compatibility with a wide range of fuse holders in both panel-mount and board-mount configurations. The transparent enclosure not only contributes to electrical insulation but also allows for clear visual inspection, making maintenance and troubleshooting much easier and more efficient.
Featuring a 'T' (time delay or slow blow) speed characteristic, this cartridge fuse can tolerate short-duration inrush currents that are common in devices with motors or transformers while still providing reliable circuit protection in the event of sustained overcurrent. Its low breaking capacity design means that, in the event of a fault, the fuse will open the circuit safely without causing secondary damage to nearby components, making it suitable for non-critical circuits where lower interrupt rating is acceptable.
The 563-621 fuse supports a wide operating temperature range from - 55°C to 125°C, ensuring stable performance under demanding environmental conditions. Compliance with multiple international safety and quality standards, including VDE, CSA, RoHS, and UL, means this fuse can be specified confidently into industrial, commercial, residential, and automotive power applications worldwide.
Whether used in control panels, HVAC equipment, consumer electronics, or process automation systems, the RS PRO glass cartridge fuse provides a reliable, cost-effective solution for circuit protection. Its VBS series lineage ensures consistent manufacturing quality and trusted performance across applications.
