Pyro Fuse
Pyro Fuse (Pyro Safety Switch) is a safety device specifically designed for high-voltage electrical systems and is widely used in electric and hybrid vehicles. It utilizes a pyrotechnic mechanism to rapidly and irreversibly disconnect the circuit in emergency situations (such as collisions), effectively protecting the system and personnel from electrical hazards.

Limitations of Traditional Semiconductor DC Fuses
High Temperature Rise and Power Consumption
To ensure the breaking speed of the short circuit, part of the current density of the narrow dia. is designed to be very high, so that the temperature rise and power loss of the fuse at the rated current are relatively high.
Existence of The Protection Blind Sopts
To reduce the temperature rise and power loss, the fuse usually needs to be used with reduced capacity, and the fuse itself has a minimum reaking current, making the very lower overload current a protection blind spots.
Single Protection Feature
The protection characteristics of the fuse are determined by the structural size, limited by the rated voltage and current, so it is difficult to flexibly adjust according to the application scenario and protection requirements.
