Integrator’s terse spec recap
The Siemens SENTRON 3VA2063-5HL32-0DL0 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 that ceiling. Breaking capacity hits 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V, so it handles high-fault utility feeds in North American and IEC 50 kA-class installations without cascading upstream.
Line protection build and auxiliary complement
That gives the panel builder remote status and trip indication without adding external relays. Dimensions are 105 mm wide, 181 mm high, 86 mm deep — standard SENTRON 3VA frame size for 63 A.
