At 30 °C ambient the breaker holds a full 16 A. At 40 °C it derates to 15.15 A, at 45 °C to 14.72 A, and at 55 °C to 13.79 A. If your panel runs warm — say near a transformer or a row of contactors — size the load to the derated value at your actual ambient, not the 30 °C number. Mounting position is any — vertical, horizontal, or upside-down — so it fits tight enclosures without worrying about orientation. Terminal protection is IP20 with conductors connected; keep bare fingers away from the live terminals.
