Product details

What the 85 kA Icu means for your panel

The C10V45E040 is a ComPacT NSX100HB1 frame MCCB, 4-pole, rated 40 A at 40 °C with a MicroLogic 5.2 E electronic trip unit. Its headline breaking capacity is 85 kA Icu at 500 V AC 50/60 Hz per IEC 60947-2, stepping to 80 kA at 525 V and 75 kA at 690 V. The electronic trip unit provides L (long-time overload), S (short-time short-circuit), and I (instantaneous) protection, plus an integrated energy meter that communicates demand current, power, alarms, and time-stamped event tables.

Front connection both upside and downside simplifies bus-bar and cable routing in a panel. Width 140 mm, height 161 mm, depth 86 mm — allow that footprint plus 35 mm connection pitch for adjacent breakers.

Durability and thermal memory

Mechanical durability is 20,000 cycles; electrical durability at 440 V In is 10,000 cycles, doubling at half load. Local signalling includes a green flashing LED for ready state, red LED at 105% Ir for overload, and orange at 90% Ir.
