Product details

Overview

The C125H350FM is a Schneider ComPacT NS new generation molded case circuit breaker with 3 poles, rated 1250 A switching current and an 85 kA ultimate breaking capacity (Icu) at 690 V AC. It carries a MicroLogic 5.0 electronic trip unit providing LSI protection (long-time, short-time, instantaneous) for distribution applications. The unit is in active production, available through standard distribution channels.

Schneider lists the C125H350FM as an active, current-production part within the ComPacT NS new generation range. No end-of-life notice has been issued. For a line-down or BOM-fill requirement, an RFQ is the fastest path to confirm lead time and quantity — the part is sourced through Schneider's distribution network and typically carries a lead time of several weeks depending on volume.
