It's a 3-pole device built to EN/IEC 60947-2, meaning it's certified for industrial panel distribution and motor-circuit protection, not just residential branch circuits.
The 100 kA Icu at 690 V AC is the same rating at 500 V and 525 V — the breaker doesn't derate its interrupting capacity across the common 500–690 V industrial range. The utilisation category is A, so it's not intended for frequent switching of motor loads under load — that's what a contactor does. This breaker sits in the distribution path, protecting the cable and downstream devices.
The TM-D trip unit gives you L (thermal) overload protection and I (magnetic) short-circuit protection. No ground-fault module — the earth-leakage protection is listed as 'Without', so if you need GFCI on this feeder, you add a Vigi module externally. The magnetic pickup is fixed on the TM-D — not adjustable — so verify that the instantaneous trip threshold coordinates with your downstream branch breakers.
Mounts flat on a backplate — no DIN rail adapter here. The 105 mm width and 161 mm height fit the standard ComPacT NSX cutout. The toggle handle gives positive visual indication of the contact position.
