A fusing mechanism that safely breaks an electronic circuit

The mechanism does not break the circuit when detecting an inrush current generated upon switching on the power supply but definitely breaks the circuit when detecting continuous abnormal current flows.

Internal structure/shape

The product’s heat storage is controlled by adopting the laser trimming method and developing a proprietary heat-insulating material. This allows the product to combine inrush-resistance characteristics and reliability.
