MCCB for distribution duty, 1000 A frame
It is rated 1000 A at 50 °C and carries an IEC 60947-2 breaking capacity of 50 kA Icu at 415 V AC (50 kA code N).
The MicroLogic 5.0 A provides LSI protection (long-time overload, short-time short-circuit, instantaneous short-circuit) plus an integral ammeter and thermal memory (20 min reset). Mechanical durability is 10 000 cycles; electrical durability ranges from 2000 cycles at rated current up to 6000 cycles at half-rated current, which governs maintenance intervals in high-switching applications.
Fixed mounting on a backplate, with front connections both upside and downside at a 70 mm pitch. The breaker measures 327 mm high × 210 mm wide × 147 mm deep. IP40 front face (IK07 impact) suits enclosed panel installation—not rated for washdown. The LCD display and four red fault LEDs plus one yellow overload LED give local status without opening the door.
