The 3VA2163-6HL36-0DC0 is a SENTRON 3-pole molded case circuit breaker rated for 63 A continuous at 40 °C, with an ETU320 electronic trip unit handling line protection.
Above that, it steps down: 60.6375 A at 55 °C, 58.275 A at 60 °C, 55.9125 A at 65 °C, and 53.55 A at 70 °C.
Panel fit — dimensions and auxiliaries
Footprint is 105 mm wide, 181 mm tall, 86 mm deep — standard SENTRON 3VA form factor for 3-pole frames up to 63 A. The two HQ auxiliary switches (3VA9608-0BB25 integrated) and the undervoltage release (UVR) are factory-fitted; no field-assembly required for those.
What the ETU320 release does
The ETU320 is an electronic overcurrent release with fixed settings — no field-adjustable dials. It provides long-time and short-time protection plus instantaneous trip for line protection duty. The 20 000 mechanical endurance cycles cover typical panel-switching life for a main or feeder breaker.
