The C10B6TM032 is a Schneider Electric ComPacT NSX100B molded-case circuit breaker, 4-pole, rated 32 A at 40 °C with a TM-D thermal-magnetic trip unit. It's built to EN/IEC 60947-2, so it's rated for distribution duty — not just motor protection, but feeder and main-switch applications where you need the isolation capability it carries (yes, suitability for isolation is listed). The 25 kA Icu at 380/415 V AC is the number that matters for most 400 V-class panels; at 240 V it jumps to 40 kA, and at 500 V it still holds 15 kA. That's Category A (no intentional short-time delay), which means it's a fast-acting breaker for branch or main where you're coordinating upstream, not doing selective tripping with a delay.
What the 32 A TM-D trip means on the line
The TM-D trip unit gives you thermal protection (L) for overloads and magnetic protection (I) for short circuits — no ground-fault built in, so if you need earth-leakage, you add a Vigi module externally. The magnetic pickup is fixed (not adjustable), so the short-circuit trip threshold is set at the factory. That's typical for a TM-D — it's a workhorse trip for general distribution, not a fancy electronic unit with adjustable curves. Compared to the electronic Micrologic trip units in the same NSX frame, the TM-D is simpler, cheaper, and doesn't need a power supply to operate the trip mechanism.
