Protection in milliseconds.
Avoid short-circuits, prevent fires, and strategically drain stranded energy with our pyro fuses for low and high voltage applications.
Autoliv's pyro fuses contribute to safe and reliable operations of electrical systems. They break current and prevent fire in case of electrical malfunction or vehicle crash events. For low and high voltages up to 1,000 V, our pyro fuses work flawlessly even in challenging conditions. With heritage and extensive knowledge in automotive safety, we currently supply our products to a large number of light vehicle OEMs. Contact us today to discuss how we can meet your needs.
Pyro fuses are irreversible, mechanical switches cutting the current in critical situations where electrical safety is vital. The pyro fuse is activated by an external signal from the BMS or airbag control unit, triggering the release of pyrotechnic energy pushing a piston to sever the busbar. The flow of electric current ceases instantly.
Autoliv's Pyro Safety Switches are pyro fuses ensuring electrical safety in milliseconds by:
Autoliv's pyro fuses protect all low and high voltage systems that produce, store and convert electricity. Examples of application areas include:
EXTREMELY QUICK RESPONSE - Switching-off in tenths of milliseconds, effectively mitigating electrical hazards
IRREVERSIBLE - One-time activation ensuring unambiguous function and post-event analytics
RELIABILITY - No deterioration over time, robustness and ability to operate flawlessly even in challenging environments
PRECISION & PREDICTABILITY - Highly controlled and individually designed triggering conditions meeting the requirements of each case
CURRENT LEVEL INDEPENDENCE - Flawless function in both over-, under- and normal current level triggering events
COST AND SPACE EFFICIENCY - Minimizing the need for component volume and cost due to its constant size independent of voltage levels
