Full 32 A rating holds at 35 °C ambient. At 40 °C it derates to 30.72 A; at 50 °C to 29.41 A; at 60 °C to 28.03 A. That's a linear drop of about 0.4 A per degree above 35 °C — factor it in if the panel runs hot. Operating range spans -40 °C to 75 °C, with humidity limits of 95% up to 55 °C, tapering to 35% at 75 °C.
15 kA per EN 60898 and 25 kA per IEC 60947-2. The EN rating applies to standard distribution boards; the IEC rating covers industrial installations where higher prospective fault current is expected.
Four modular width units — 72 mm wide, 90 mm tall, 76 mm deep (70 mm installation depth). Snaps onto DIN rail in any mounting position.
