RS PRO 4A T Glass Cartridge Fuse, 5 x 20mm, Предохранитель

RS PRO 4 A Glass Cartridge Fuse, 5 x 20 mm, Speed T

This RS PRO cartridge fuse will protect your wiring and electrical equipment in the event of a short circuit. It works by blowing and cutting off the current flow when it gets too high. Fuses like this one are an essential safety component for both residential and commercial settings.


This cartridge has a glass body that makes it easy to tell when it has blown. It's a T-rated fuse, meaning it's able to handle high bursts of current for short periods of time without blowing. As it's a low breaking capacity (LBC) fuse, it's best suited to low-voltage applications.


You can use this fuse in a wide range of settings as it functions at temperatures from -55ºC to +125ºC. It's commonly used for air-conditioning systems, cars and refrigerator pumps.
