The Siemens SENTRON 3VA2163-5HL32-0KL0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to the 70 °C operating maximum. That flat thermal curve simplifies panel sizing in warm enclosures or near other heat sources. Its interrupting ratings climb to 187 kA at 240 V, drop to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 3.7 kA at 690 V.
Line protection design with integrated accessories
This variant is configured for line protection — the base design of the product is protection of the feeder or branch circuit, not motor or generator protection.
