DC-rated miniature circuit breaker for 80 A loads
At 35 °C it carries 80 A; derate to 76 A at 40 °C, 73.92 A at 45 °C, 71.84 A at 50 °C, and 69.6 A at 55 °C — the thermal derating curve is published, so you can size it for elevated panel temperatures without guessing.
Installation depth is 70 mm.
Halogen-free and silicon-free construction. Ambient operating range spans -40 °C to 75 °C, with humidity limits of 95% up to 55 °C, 55% up to 70 °C, and 35% at 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Sealable terminals (top and bottom combined terminals) support tamper-proofing for metering or critical circuits.
