What it is and what it does
The C11F3TM032L is a Schneider Electric ComPacT NSXm moulded-case circuit breaker, 3-pole, with a 32 A thermal-magnetic TM-D trip unit. It's rated 36 kA at 415 V AC — that's the interrupting capacity at the panel's line side, so it clears a bolted fault up to that level without welding its contacts or venting arc gas into the enclosure. The TM-D trip gives you fixed thermal and magnetic protection: the thermal element handles overloads (slow curve), the magnetic element handles short-circuits (instantaneous). It's built to EN/IEC 60947-2, the standard for industrial MCCBs, and it's listed as suitable for isolation — meaning you can use it as a visible-break disconnect downstream of the main breaker.
Where it fits in the panel
Mounts flat on a backplate — no DIN rail required, though it does occupy 9 module pitches at 81 mm wide. The front-facing Everlink lugs accept 2.5 to 95 mm² rigid copper or aluminium, or 2.5 to 70 mm² flexible copper. That's a wide wire range for a 32 A breaker, handy when you're feeding a long run with voltage-drop upsizing. Connection pitch is 35 mm with spreaders, 27 mm without — so if you're landing parallel feeds, the spreaders give you room for the lug wrench. IP40 front face, IK07 impact rating: fine for a clean indoor panel, but not for washdown zones.
