What This MCB Does in Your Panel
The C-curve (tripping characteristic class C) means it holds through inrush up to 5–10× rated current, then clears fast on hard faults. That makes it the right choice for motor starter feeders, control transformers, and lighting panels where the load draws a moderate magnetizing surge. Rated operating voltage is 400 V AC (440 V multi-phase or single-phase) and 880 V DC, with a maximum DC operating voltage of 1 000 V.
The IP20 rating applies with connected conductors — the terminals are finger-safe only when wired. Combined top and bottom terminals allow daisy-chaining busbars without extra jumpers.
Operates across -40 °C to 75 °C ambient, with humidity limits of 95% up to 55 °C, derating to 35% at 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz — survives shipping and fan vibration in industrial cabinets.
