Product details

It carries a 10 kA breaking capacity per EN 60898 and 35 kA per IEC 60947-2, so it handles high fault currents typical in industrial panels while protecting sensitive semiconductor loads — type A trips on both overcurrent and a minimum of 2–3 times rated current for short-circuit, catching peak currents from rectifier inputs or switching supplies.

The quick assembly system and combined terminals top and bottom speed panel wiring.

Halogen-free and silicon-free construction, sealable, neutral conductor switching. Ambient temperature range -40 to 75 °C with a derating curve: 2 A at 35 °C, 1.9 A at 40 °C, 1.85 A at 45 °C, 1.8 A at 50 °C, 1.75 A at 55 °C, 1.7 A at 60 °C. Humidity limits: max 95% to 55 °C, 55% to 70 °C, 35% to 75 °C.
