Product details

The trip unit is thermal-magnetic (TM-D), meaning the thermal bimetal handles overload protection and the magnetic coil handles short-circuit; the D curve gives a higher magnetic trip threshold (10–14× In) suited for loads with moderate inrush like small motors or transformers.

The 108 mm width × 137 mm height × 80 mm depth fits standard distribution panel layouts; the 12-module 9 mm pitch gives you the DIN-rail footprint count for panel planning. Connection is front-facing on both line and load sides, using Everlink lug terminals that accept 2.5…95 mm² rigid or stranded aluminium/copper, or 2.5…70 mm² flexible copper. That terminal range covers most distribution feeder and subfeed sizes. The 35 mm connection pitch with spreaders (27 mm without) is the dimension to check when wiring multiple breakers in a row. IP40 enclosure protection means it's suited for indoor panel installation — no washdown rating, so keep it behind the gland plate.

That standard covers the interrupting ratings, isolation suitability (yes, marked as suitable for isolation per IEC 60947-2), and the utilisation category A (non-delayed, for distribution use). Overvoltage category III suits fixed-installation distribution boards. The IK07 impact rating (per IEC 62262) means the enclosure resists 2 J impacts — enough for accidental tool drops during panel work. The grey RAL 7016 colour is the standard Schneider finish for this range. Compliance documentation (declaration of conformity, IEC test reports) is available from Schneider's product documentation portal; the part carries CE marking for the European market.

Frequently asked questions

What is the breaking capacity of C11N6TM040L?

The performance level is N, rated at 50 kA at 415 V AC. That's the maximum fault current the breaker can safely interrupt at that voltage.

What terminals does the C11N6TM040L use and what wire sizes fit?

Everlink lug terminals on both line and load sides. Accepts 2.5…95 mm² rigid or stranded aluminium/copper, and 2.5…70 mm² flexible copper.

Where can I buy C11N6TM040L and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the difference between the NSXm and the full-size NSX?

The NSXm is the compact frame — smaller footprint (108 mm wide vs the NSX's wider frame) and a lower maximum current rating (63 A frame vs 250 A or higher on the NSX). The C11N6TM040L tops out at 40 A; if your load exceeds that, step up to the full-size NSX.
