What this MCCB carries
The Siemens 3VA2063-5JQ32-0HL0 is a SENTRON molded case circuit breaker (MCCB) rated for 63 A continuous at 40 °C through 70 °C — no derating needed across that whole ambient span, which simplifies panel thermal budgeting in a hot enclosure. Three-pole construction with a full-scale trip setting of 63 A and a minimum adjustable pickup of 95 A, maximum 756 A — the wide adjust range lets you coordinate with downstream branch breakers without swapping the frame. Interrupting capacity is 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V (–). At 480 V typical for North American panels, the 121 kA figure at 440 V is the closest reference — that puts SCCR headroom well above most distribution transformer fault levels.
Physical fit
Dimensions: 105 mm wide, 181 mm tall, 86 mm deep (–). Fits standard panel-mount cutouts for SENTRON 3VA frames; the 105 mm width is the same as other 3VA2 three-pole breakers, so a panel laid out for a 3VA1110 variant will accept this one without re-drilling.
