Overvoltage category III confirms it is rated for fixed-installation distribution boards, not just downstream equipment. ## Thermal derating and ambient range The 2 A rating holds at 35 °C ambient. Above that, derate: 1.85 A at 40 °C, 1.78 A at 45 °C, 1.69 A at 50 °C, 1.61 A at 55 °C (–). Width is 18 mm — one modular unit.
