That makes it a straightforward drop-in for a 63 A feeder or main breaker in a panel that sees elevated internal temperatures. Breaking capacity is 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. The N-conductor protection is configurable — adjustable OFF or 100% of the phase current — which matters for 4-wire systems where the neutral may need full-rated protection or none. No undervoltage release, no shunt trip (voltage trigger), no communication module, and no ground-fault monitoring are fitted on this variant. If any of those are needed, the order code must be adjusted to a version that includes them.","metaTitle":"SENTRON 3VA2163-5HN42-0AA0 MCCB, 63 A, 4-Pole, 187 kA at 240","metaDescription":"SENTRON 3VA2163-5HN42-0AA0 molded case circuit breaker, 63 A continuous, 4-pole, ETU350 release.
