Product details

The C11B6TM080B is a Schneider Electric ComPacT NSXm moulded-case circuit breaker (MCCB), 4-pole, rated 80 A at 40 °C with a thermal-magnetic TM-D trip unit. Its breaking capacity is 25 kA at 415 V AC (performance level B), which means it can safely interrupt a fault current up to that level without upstream damage — sized for distribution panels where the available fault current is known to be under that threshold. The part is certified to EN/IEC 60947-2, the standard for low-voltage switchgear and controlgear, so it meets the requirements for isolation and overcurrent protection in commercial and industrial installations.

Mounting and integration

Mounts on a backplate (not DIN rail), in horizontal or vertical orientation, flat on the back. The 108 mm width occupies 12 module pitches at 9 mm. Connection is front-to-front via compression lugs or busbars — no rear-access needed, which simplifies panel layout and gland-plate planning. Neutral is on the left, and the connection pitch is 35 mm with spreaders or 27 mm without. Pollution degree 3 per IEC 60664-1 means it's rated for industrial environments where conductive pollution or condensation can occur.
