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.

Low-cost, fast-acting protection switch disconnects the circuit safely, reliably, swiftly, and efficiently, shutting down the power circulation before any short circuit can occur due to vehicle deformation in the case of a crash, accident, or malfunction.
The protection strategy can be adjusted according to the application scenario
Advanced breaking metrics:
1000V/15000A/15μH
800V/20000A/13μH
Reliable Breaking of All Faults, Low Rated Power Consumption, Can Bear Impulse Current
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.
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.
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.
Pyro fuses offer millisecond response times and compact design, making them critical for the safety and compliance of next-generation Energy Storage Systems.
