Product details

The Schneider Electric C16B3TM080 is a ComPacT NSX160B moulded-case circuit breaker with a thermal-magnetic TM-D trip unit, rated 80 A at 40 °C, three poles, and a breaking capacity of 25 kA Icu at 415 V AC (50/60 Hz) per IEC 60947-2. It is suitable for isolation per the same standard, meaning it can serve as a disconnecting means in a distribution panel when the handle is padlocked off.

At 240 V the breaker can interrupt 40 kA Icu, which covers high-fault service entrances in North American panels. The 20 kA Icu at 440 V and 15 kA at 500 V give headroom for 480 V delta systems common in motor control centres.

Mounts flat on a backplate in horizontal or vertical orientation. Front-facing connections on both line and load sides simplify busbar and cable routing in a panel. The 35 mm connection pitch matches standard DIN-rail terminal blocks for outgoing feeders.

Frequently asked questions
