63 A MCCB with full-temperature rating and high interrupting capacity
The Siemens SENTRON 3VA2163-6HN36-0AB0 is a 3-pole molded case circuit breaker rated for 63 A continuous current across the full operating temperature range from -25 °C to 70 °C — no derating needed from 40 °C through 70 °C, which simplifies panel design in warm cabinets or outdoor enclosures. Interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V — that 242 kA at 240 V tells you this breaker is sized for high-fault utility or transformer-fed service entrances where available fault current is substantial.
Line protection with auxiliary switch integration
Dimensions are 181 mm high, 105 mm wide, 86 mm deep — the 105 mm width is standard for a 3-pole MCCB in this frame size, so it drops into existing SENTRON or competitor panel cutouts without re-drilling the gland plate. Maximum power loss is 4 W, which keeps internal cabinet heating low even in densely packed enclosures — relevant for thermal coordination in sealed NEMA 4X or IP65 boxes.
