The Schneider Electric C10B6TM080C is a ComPacT NSX100B moulded-case circuit breaker (MCCB) with a 4-pole configuration and a thermal-magnetic TM-D trip unit rated at 80 A at 50 °C. It is designed for distribution applications and carries a breaking capacity of 25 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, with higher ratings at lower voltages (40 kA at 220/240 V). The B breaking-capacity code (25 kA at 415 V) tells you this unit is sized for standard industrial panel secondary distribution — not for main service entrance where higher SCCR is typically required. The thermal element handles sustained overloads; the magnetic element clears high-fault currents. This is a Category A breaker (no intentional short-time delay), so it trips instantaneously on magnetic pickup — suitable for feeder circuits where selectivity with downstream devices is achieved by current grading rather than time delay.
The C10B6TM080C is listed as current-production (active lifecycle stage). No end-of-life notice or last-time-buy date is available.
No earth-leakage protection module is integrated; if ground-fault protection is needed, an external Vigi add-on block is required.
Durability and operating conditions
Mechanical endurance is 50,000 cycles; electrical endurance at 440 V In is 30,000 cycles, doubling to 50,000 at half-rated current. These figures suit frequent-switching applications like conveyor or pump feeder circuits. The neutral position is left; the neutral protection setting is 3D (no protection on the neutral pole) — confirm the system grounding scheme before specifying.
