The 15 A rating holds at 30 °C and 40 °C ambient; above that it derates to 14.6 A at 45 °C, 14.1 A at 50 °C, 13.6 A at 55 °C, and 13.2 A at 60 °C, so factor your panel ambient into the load calculation.
Width is 36 mm (2 modular units), depth 70 mm, height 121 mm. Snaps onto standard mounting rail (DIN rail) in any position. Sealable, so a panel lockout tag can be applied after commissioning.

The D-curve (10–20× In magnetic trip) is designed for loads with high inrush current: motors, transformers, welding equipment, and discharge lighting. It prevents nuisance tripping on startup surges while still providing short-circuit protection.
