The Siemens 3VA2163-8HL46-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for 63 A continuous current, with four poles and an ETU320 electronic trip unit. It is designed for line protection in distribution panels, sized to fit a 140 mm wide by 181 mm tall by 86 mm deep footprint.
This MCCB delivers a rated breaking capacity of 330 kA at 415 V and 440 V, 440 kA at 240 V, 220 kA at 500 V, and 52.5 kA at 690 V.
Trip unit and thermal performance
The breaker's continuous current rating holds at 63 A across the full ambient temperature range from 40 °C to 70 °C — no derating needed within that band.
Physical integration
The breaker occupies a 140 mm width, 181 mm height, and 86 mm depth. Front face protection is IP40. No undervoltage release, no communication function, and no ground-fault monitoring version are fitted on this variant.
