Fuses & Fuse Accessories
Protect Your Electronic Components
Whether in power distribution units, battery systems, or onboard chargers – reliable overcurrent protection is essential to safeguard sensitive components, prevent malfunctions, and meet the highest standards of safety and reliability.
Overcurrent and overload conditions are not limited to industrial environments, they also occur frequently in automotive applications and consumer electronics. Using the right fuse and fuse accessory is not only a technical necessity but also a key factor in complying with current and future industry standards.
Samples Contacts NewsExplaining Fuses
A fuse is an overcurrent protection device that interrupts the circuit by melting a wire. Decisive for this are the current intensity and the duration of exposure.
The parameters for a fuse are for example:
- Voltage rating (AC or DC)
- Current rating
- Normal operating current
- Ambient temperature/s
- Overload conditions and opening times
- Melting Integral (I2t)
- Surge and Pulse current characteristics
- Physical sizes and available board space
- Standards requirements
Fuse Accessories
Many commonly available electronic fuses cannot be dropped into conductive paths due to their shape and size. Typically, a fuse accessory is required to integrate these fuses with a couple of primary functions: integrate fuses safely in electrical circuits, ensure a robust current path (voltage does not creep to other components) and provide a method to replace fuses once they manage overcurrent events as intended.
A few common components of fuse accessories can be defined as follows:
- Terminals are responsible for both accepting current from the circuit into the fuse accessory and delivering it back to the circuit.
- Contacts are responsible for engaging with the fuse to deliver current to and from the fuse, often in the form of a clip or an eyelet.
- Additional components can be found in various fuse holders, but they depend on the product type.
