Overview
The C12H6TM125L is a Schneider ComPacT NSXm molded case circuit breaker with 4 poles, rated 125 A at 40 °C, and a breaking capacity of 100 kA at 440 V AC. It uses a TM-D thermal-magnetic trip unit and complies with EN/IEC 60947-2. This unit is in active production and available through standard distribution channels.
Lifecycle & availability
Schneider lists the C12H6TM125L as an active part within the ComPacT NSXm range, with no announced end-of-life. For a BOM freeze or line-down need, an RFQ confirms current lead time and quantity. The closest functional peer is the C12F6TM125L, which shares the same 4-pole, 125 A rating and 100 kA IC, but uses a different trip unit type (TM-D vs. TM-D) — verify trip curve compatibility before substitution.
