Product details

The Schneider Electric C11E6TM040B is a ComPacT NSXm moulded-case circuit breaker (MCCB) with a 40 A thermal-magnetic TM-D trip unit, 4 poles, and a 16 kA breaking capacity at 415 V AC (performance level E). The TM-D trip unit is thermal-magnetic: the thermal bimetal handles overload protection (inverse-time curve), and the magnetic coil handles short-circuit instantaneous tripping. At 40 A and 40 °C ambient, it's sized for feeder or branch protection on 50/60 Hz AC networks.

The lifecycle stage is listed as current — this is an active-production part within the ComPacT NSXm family. No end-of-life notice or successor has been published.

Mounts on a backplate (not DIN rail) in either horizontal or vertical orientation, flat on the back. At 137 mm high, 108 mm wide, 80 mm deep, and occupying 12 module pitches at 9 mm each, it fits standard panel cutouts for the NSXm frame. Connection terminals accept compression lugs or busbars; front-connect both top and bottom simplifies busbar stacking in multi-breaker panels.

Rated IP40 (finger protection) and IK07 (impact resistance). Humidity range 0–95%.

Frequently asked questions

How do I get current pricing and availability for C11E6TM040B?

Submit an RFQ against this part. Pricing and stock are confirmed at quote time through independent distribution channels — no automated stock figure is published here.

What is the closest alternative to C11E6TM040B in the ComPacT family?

Within the ComPacT NSXm range, a 40 A 4P breaker with a different breaking capacity (e.g., 25 kA or 36 kA) or a different trip unit (Micrologic electronic) would be the parametric alternative. No pin-compatible drop-in exists outside the same NSXm frame; the TM-D trip unit and 16 kA E performance level define this variant.

What is C11E6TM040B's listed range?

It belongs to the ComPacT range, specifically the ComPacT NSXm sub-family — a compact MCCB line for distribution applications.

What colour is C11E6TM040B?

Grey (RAL 7016).

What compliance documentation does Schneider provide for C11E6TM040B?

The breaker is certified to EN/IEC 60947-2, rated for isolation per that standard, and carries pollution degree 3 and overvoltage category III ratings. RoHS and REACH declarations are typically available from Schneider's documentation portal for the ComPacT NSXm series.
