Schneider C16N3 ComPacT NSX160N Trip Unit 3P

The Schneider Electric C16N3 is a ComPacT NSX160N 3-pole basic frame circuit breaker rated at 160 A, designed for electrical power distribution applications. Supplied without a trip unit, this bare chassis accepts a separately ordered protective unit to suit specific installation requirements. Its ultimate short-circuit breaking capacity reaches 50 kA at 380/415 V AC, making it well suited to demanding industrial and commercial switchboard applications.
