Two poles protected, fixed-mount, front-connected — standard panelboard or switchboard fit. The S breaking capacity code means 70 kA Icu at 415 V AC, which is the figure that governs most 400 V distribution boards; the headline 100 kA Icu at 240 V AC applies on lower-voltage services. At 690 V AC the rating drops to 10 kA Icu, so it's not a candidate for 690 V main feeders unless the fault current is known to be below that. The thermal-magnetic TM-D provides L (overload) and I (short-circuit) protection curves — no electronic adjustment, no earth-leakage add-on.
IK07 impact rating covers accidental tool drops during commissioning.
