What the 600 A rating and 36 kA breaking capacity mean for your panel
The 36 kA Icu at 380/415 V AC per EN/IEC 60947-2 is the interrupting rating that governs fault clearance in a 400 V distribution board — that figure, not the higher 40 kA at 240 V, is the one to coordinate with your upstream transformer impedance and downstream panel SCCR. The breaker carries a Category A utilisation class, meaning it is not intended for selective coordination with a downstream short-delay trip; plan your selectivity scheme accordingly.
Mounting and integration into a switchboard
Mounts on a backplate or DIN rail in horizontal or vertical orientation.
Durability and isolation capability
Mechanical endurance is rated at 15,000 cycles; electrical endurance reaches 8,000 cycles at 440 V at half rated current, and 4,000 cycles at full 600 A. The breaker is certified for isolation use per EN/IEC 60947-2 — the contact position indicator gives a visible gap confirmation for lockout/tagout procedures. The TM-D trip unit provides thermal overload protection (L) and fixed magnetic short-circuit protection (I); no earth-leakage module is integrated.
