The Siemens 3VA2163-5HL36-0HA0 is a SENTRON 3-pole molded case circuit breaker (MCCB) rated for line protection duty. It carries a continuous current rating of 63 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Interrupting capacity hits 187 kA at 240 V AC, stepping down to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That 187 kA figure at 240 V puts it in the high-fault tier for North American panelboards where available fault current runs high.
Current setting range and selectivity
The electronic trip unit adjusts from 95 A minimum to 756 A maximum — that's a roughly 8:1 range, which gives the specifying engineer room to coordinate downstream feeders without swapping the breaker frame. The 63 A continuous rating is the thermal base; the adjustable trip covers the overload and short-circuit thresholds within that window. For a 480 V distribution panel, the 121 kA interrupting at 415 V/440 V means it can sit ahead of a 100 kA-rated downstream MCCB and still hold coordination.
Shunt trip and auxiliary release
This variant includes a shunt trip release (STL) for remote tripping — a key feature for emergency-stop circuits or supervisory control schemes that need to open the breaker from a PLC or safety relay. The shunt trip is voltage-triggered (confirms a voltage trigger). No undervoltage release is fitted, so the breaker stays closed on control power loss unless the shunt trip is explicitly energized. That's the usual choice for applications where you don't want a nuisance trip on a 24 VDC dip.
Physical fit and panel integration
Dimensions: 105 mm wide, 181 mm high, 86 mm deep. That 105 mm width is a standard 4-pole MCCB footprint for a 3-pole frame — it occupies the same DIN-rail or mounting-plate real estate as other SENTRON 3VA2 three-pole units. The 86 mm depth keeps it within typical 200 mm deep enclosure clearances. Rated insulation voltage is 800 V, so it's suitable for 480 V and 600 V class systems with margin.
