Product details

Part identification and key ratings

The C11H6TM080B is a Schneider Electric ComPacT NSXm moulded-case circuit breaker (MCCB) rated 80 A at 40 °C, 4-pole, with a TM-D thermal-magnetic trip unit. It carries a 70 kA breaking capacity at 415 V AC (performance level H), making it suitable for distribution boards where high fault-current headroom is required per EN/IEC 60947-2.

The 80 A rating at 40 °C is the continuous current the breaker carries without tripping in a 40 °C ambient — derate for higher enclosure temperatures.

Deployment context

Mounts on a backplate in horizontal or vertical orientation; the 108 mm width (12 module pitches) fits standard DIN-rail enclosures with a backplate adapter. Front connections accept compression lugs or busbars.

Frequently asked questions

What is the breaking capacity of C11H6TM080B?

The C11H6TM080B has a 70 kA breaking capacity at 415 V AC (performance level H), compliant with EN/IEC 60947-2.

What trip unit does C11H6TM080B use?

It uses a TM-D thermal-magnetic trip unit rated 80 A at 40 °C, with fixed overload and short-circuit protection curves.

What compliance documentation does C11H6TM080B carry?

The breaker is compliant with EN/IEC 60947-2, suitable for isolation per that standard, and carries pollution degree 3 and overvoltage category III ratings per IEC 60664-1.
