• Improved safety: Provides a safe and reliable means of overcurrent protection.

Additional Details

The H145R16-50 is characterized by its voltage rating, current rating, and interrupting rating. The 50 likely indicates the current rating in Amperes. The voltage rating is a critical parameter and should be selected based on the application's voltage requirements. The fuse's I2t value indicates its ability to limit the energy let-through during a fault. Precise specifications, including voltage rating, interrupting rating, I2t value, and dimensions, can be found in the Eaton Bussmann datasheet for the H145R16-50.
