Product details

The C6344A570 is a MicroLogic 4.3 AL electronic trip unit for the ComPacT NSX400...630 range, rated 570 A at 40 °C. It provides LSoI protection — long-time overload, short-time short-circuit with fixed delay, and instantaneous short-circuit — with integrated earth-leakage protection (Class A).

Protection and adjustments

Long-time pickup (Ir) is adjustable from 250 to 570 A, with fixed time delays: 400 s at 1.5 x Ir, 16 s at 6 x Ir, and 11 s at 7.2 x Ir. Short-time pickup (Isd) adjusts from 1.5 to 10 x Ir with a fixed delay. Instantaneous pickup (Ii) is fixed at 6900 A. Earth-leakage sensitivity (IΔn) and time delay (Δt) are both adjustable.

The trip unit mounts fixed in a 4-pole ComPacT NSX400...630 breaker frame, neutral on the left. It is rated IP40 (finger-safe) and operates from -25 to 70 °C, storing from -50 to 85 °C. Local signalling includes a green flashing LED for ready, red/orange LEDs for overload at 105% / 90% Ir, and a yellow indicator for residual current.
