It carries a MicroLogic 6.0 electronic trip unit that provides L (long-time overload), S (short-time short-circuit), I (instantaneous short-circuit), and G (ground fault) protection — so a single device covers thermal, magnetic, and earth-leakage coordination without external relays. The 85 kA Icu at 240 V AC (50 kA at 415 V) means it can safely interrupt fault currents up to that level under IEC 60947-2, which is the standard for low-voltage switchgear and controlgear.
Fixed-mount design on a backplate, 327 mm high by 280 mm wide by 147 mm deep. The 70 mm connection pitch and front-facing terminals on both line and load sides simplify busbar alignment and cable entry in a panel. IK07 impact rating (conforming to EN 50102) handles accidental tool drops during maintenance.
The 20-minute thermal memory means the trip curve remembers prior heating events for that window, which prevents nuisance tripping on repetitive inrush while still protecting against sustained overloads.
