Product details

The C10F4TM040 is a Schneider Electric ComPacT NSX100F moulded-case circuit breaker, 4-pole, rated 40 A at 40 °C with a TM-D thermal-magnetic trip unit. It carries an 85 kA Icu breaking capacity at 240 V AC and 36 kA at 415 V AC, per EN/IEC 60947-2.

Breaking capacity and what it means for your panel

For a 480 V AC panel (common in North America), the UL 60947-4-1 listing shows 25 kA Icu — enough for most downstream feeder applications. If you need selective coordination, you'd step up to a ComPacT NSX with an electronic Micrologic trip unit.

Mounting and integration into a panel

Mounts to a backplate — not a DIN rail — via the four M6 or M8 bolts through the base. The 140 mm width and 161 mm height fit the standard ComPacT NSX cutout; depth is 86 mm. Front connections both top and bottom simplify bus-bar or cable landing. IP40 enclosure protection means it's suited for a clean indoor panel; IK07 impact rating handles accidental tool drops during commissioning.

The C10F4TM040 is listed as current production. It is a standard catalogue item in the ComPacT NSX range.

Frequently asked questions

What compliance documentation does Schneider provide for C10F4TM040?

The breaker is certified to EN/IEC 60947-2 and UL 60947-4-1. It carries IP40 and IK07 ratings. RoHS and REACH declarations are standard for the ComPacT NSX range; request them with your RFQ.
