The TM-D unit provides L (thermal) overload protection and I (magnetic) short-circuit protection, so it handles motor inrush and distribution feeder duty equally. Breaking capacity is where this part earns its place in the panel. At 415 V AC — the most common industrial distribution voltage — it delivers 36 kA Icu. For a 400 V panel with a transformer upstream that can deliver 35 kA of fault current, this breaker holds coordination without cascading to the main. The 4-pole (4P) configuration with neutral on the left and no integral earth-leakage module means this is a straight distribution or feeder breaker — not a GFCI. Neutral protection is set to 3D (no protection), so the neutral pole is switched but not monitored for overcurrent; confirm your system grounding design before specifying.
Mounting and integration — backplate, front connections, IP40
Front-facing connections for both line and load sides simplify bus-bar routing and cable entry in a standard panel layout. IP40 and IK07 mean it is protected against tools and wires >1 mm and against 0.5 J impacts — fine for a clean indoor panel, not for washdown zones. Five equipment slots allow auxiliary contacts, shunt trips, or an under-voltage release to be added without removing the breaker from the panel.
Lifecycle and sourcing — active production, quoted to order
Lifecycle status is current — Schneider continues to manufacture the ComPacT NSX range. This is not a phase-out or NRND part. For volume purchases or BOM-line commitments, submit a request with target quantity and delivery window.
Compliance and approvals — IEC 60947-2, isolation suitability
Certified to EN/IEC 60947-2 with utilisation category A — suitable for distribution, not for motor starting under load.
