The Schneider Electric C10M1TM025 is a ComPacT NSX100M circuit breaker, 1-pole, rated 25 A at 40 °C with a TM-D thermal-magnetic trip unit. The 1P format with toggle control and front connections makes it a direct swap in a fixed-mount panel layout.
The TM-D trip provides L (thermal overload) and I (magnetic short-circuit) protection — the thermal element handles sustained overloads, the magnetic element trips instantaneously on high faults. Overvoltage category IV confirms it's suitable for main distribution panels at the service entrance, not just downstream sub-panels. The IP40 enclosure protection keeps out tools and small objects but not water; mount it inside a sealed cabinet for washdown areas. Mechanical durability of 20,000 cycles and electrical durability of 20,000 cycles at 277 V at half rated current (In/2) or 10,000 cycles at full rated current give a realistic service life for a distribution breaker — it's not a motor-switching contactor, but it handles occasional load-break operations without accelerated wear.
Fixed-mount on a backplate, 35 mm width per pole, 161 mm height, 86 mm depth.
