Overview
The C16B47E160 is a 4-pole ComPacT NSX molded case circuit breaker rated 160 A at 40 °C, fitted with a MicroLogic 7.2 E electronic trip unit that provides overload (L), short-time (S), instantaneous (I), and earth-leakage (R) protection on a 440 V AC network. Its 40 kA breaking capacity (Icu) at 440 V AC suits distribution panels where fault levels reach that threshold; the 4-pole design with neutral on the left handles three-phase plus neutral circuits without an additional neutral disconnect.
How it compares
The C16B47E160 carries 4 poles and a 160 A frame; the 3-pole C16B3 is rated 15 kA at 690 V AC and lacks the earth-leakage trip unit, so the C16B47E160 is the correct choice when a 4-pole, 160 A, earth-leakage-protected breaker is specified.
