Switch Fuse Unit (SFU) with FuseSwitch Fuse Unit (SFU) is an electrical device that combines the functions of a switch and a fuse into a single unit. SFUs are designed to provide both switching capabilities (manually connecting or disconnecting the electrical supply) and overcurrent protection (protecting the circuit from damage due to short circuits or overloads).
How it works
How it works
- Switch: The SFU incorporates a manual switch allowing for the intentional opening or closing of a circuit, useful for tasks like maintenance or emergencies.
- Fuse: An integrated fuse element acts as a safeguard. If the current flowing through the circuit exceeds the predetermined rating of the fuse (due to an overload or short circuit), the fuse element will melt, breaking the circuit and preventing damage to the connected equipment.
Fuses commonly used in SFUs
- Rewireable fuses
- HBC (High Breaking Capacity) fuse links (also known as cartridge type fuses)
Key features and applications
- Protection: SFUs offer reliable protection against both overloads and short circuits.
- Isolation: The switch function allows for safe isolation of a circuit for maintenance or emergencies.
- Applications: SFUs are used in various settings, including:
- Low and medium voltage distribution systems.
- Industrial panels
- Main switchboards
- Residential applications
