Product details

Overview

The C16F1TM125 is a Schneider ComPacT NSX molded case circuit breaker with a single pole, rated 125 A at 277 V AC. Its TM-D thermal-magnetic trip unit provides LI protection (overload and short-circuit) and the interrupting capacity is 18 kA at 277 V AC per IEC 60947-2. This is a fixed-mount, toggle-actuated unit suitable for distribution applications. The part is in active production.

Schneider lists the C16F1TM125 as an active, current-production part with no end-of-life notice.
