The C100H460FM is a Schneider Electric ComPacT NS new generation manually operated circuit breaker, 4 poles, with a 1000 A MicroLogic 6.0 electronic trip unit. It's built for distribution duty in switchboards and panelboards, rated per EN/IEC 60947-2.
Mounts fixed to a backplate — no DIN rail here. The 327 mm height, 280 mm width, and 147 mm depth mean it needs a substantial cutout in the gland plate; plan for the 70 mm connection pitch when laying out bus bars or cable lugs. IP40 enclosure protection keeps out tools and fingers but isn't rated for washdown — install it in a dry, indoor switchboard. Front connections top and bottom simplify bus routing in a lineup. The MicroLogic 6.0 is fully electronic, so no thermal bimetal to drift; the 20-minute thermal memory matches the cooling curve of conductors after a fault.
Mechanical durability is 10,000 cycles — that's the maintenance interval to track. The four red LEDs give fault indication (overload, short circuit, ground fault, etc.) and a yellow LED signals an overload alarm — useful for a technician walking the lineup. Overvoltage category III suits fixed-installation distribution boards.
