The Siemens 3VA2163-5JP32-0HC0 is a 3-pole SENTRON molded case circuit breaker rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That 63 A holds at every temperature step in the table, so you size the feeder for a solid 63 A without thermal headroom padding. Breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. Communication function is built in — this variant talks to the control system for metering and trip-event reporting.
Mounting and integration — DIN rail or direct panel
The supplied basic switch is 3VA21635JP320AA0; the breaker ships as a complete unit with the shunt trip and aux switches pre-installed. No field wiring of the trip coil unless you need a different voltage.
