Schneider Electric C080H35AFM ComPacT NS800H 3P 800 A 70 kA MicroLogic 5.0 A Moulded Case Circuit Breaker

The Schneider Electric C080H35AFM is a 3-pole ComPacT NS800H moulded case circuit breaker rated 800 A, with a 70 kA breaking capacity (Icu) at 380/415 V AC. It is fitted with a MicroLogic 5.0 A trip unit delivering long-time overload, short-time delay and instantaneous short-circuit protection (LSI), is fixed-mounted and manually operated, and carries a 690 V rated operational voltage for industrial distribution switchboards.

Selection Notes

Its LSI trip unit adds an adjustable short-time delay (Isd/tsd) on top of long-time overload and instantaneous protection, which lets this breaker hold position in a selectivity study against downstream devices instead of tripping instantaneously on every fault. Pick the base 2.0-series LI variant instead when the circuit is a final sub-distribution feeder with no coordination requirement. The H-frame rating gives it 70 kA Icu at 380/415 V AC; within the NS800H line this is the breaking-capacity class to pick when the calculated prospective short-circuit current at the installation point is at or below that figure without derating to a higher class.
