Siemens 3VA2163-5HL36-0JL0 SENTRON MCCB — 63 A, 3-Pole, Line Protection
It's a 3-pole, line-protection design (not a motor-protective or ground-fault version), so it's sized for feeder or main breaker duty in a distribution panel, not for individual motor starting. The interrupting ratings are the headline: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. At 415/440 V it still clears 121 kA, which is well above what most industrial distribution transformers can deliver.
Physical Fit and Auxiliary Options
That's enough for remote status indication and a shunt-trip command without adding external relays. It also carries a trip indicator and a voltage trigger — so you get visual and electrical confirmation that the breaker has opened on fault, not manually. If you need those, you're looking at a different suffix on the 3VA2 family.
Environmental and Operating Range
Operating temperature: -25 °C to +70 °C. Maximum power loss is 4 W — negligible for panel thermal budgeting.
