ELECTRICAL SAFETY COMPONENTS

Successfully protecting mobility and industry

Our pyrotechnic disconnectors (pyro-fuses) and closers protect people, vehicles and electrical equipment. This protection is achieved by interrupting or short-circuiting the circuit within milliseconds in the event of a malfunction or fault.

Example uses in pyrotechnic safety:

Astotec Automotive´s pyrotechnic circuit breaker can be used to protect low and high voltage electrical systems beyond the automotive applications. Pyro fuses could also be utilized for any industrial applications in need of instant circuit isolation.

Areas of application for pyrotechnic protection:

  • Electric circuits in conventional vehicles
  • Electric vehicles
  • Energy storage devices
  • Photovoltaics
  • DC circuits in industry

Example uses in electric mobility:

  • Securing in charging & operating state in case of faults and short circuits
  • Disconnecting powertrain from battery system
  • Safe car condition post-crash for first responders and occupants
  • Short-circuiting to ensure safe vehicle condition
  • Discharging of DC link capacitor
  • Short-circuiting the drive unit
