What this MCCB carries — and where it fits
The Siemens SENTRON 3VA4160-4ED24-0AA0 is a 2-pole molded-case circuit breaker (MCCB) with a TM210 thermal-magnetic overcurrent release — LI protection (long-time and instantaneous). Rated 60 A at 40 °C, it derates cleanly through 70 °C (53 A at 70 °C), so the ampacity you spec at the panel design temperature is the ampacity you get. Interrupting capacity is 65 kA at 240 V AC and 25 kA at 480 V AC — that 25 kA at 480 V is the number your SCCR study cares about for a 480 V distribution panel; 65 kA at 240 V covers the high-fault end of a 240/120 V center-tapped service. Operating voltage is rated at 415 V AC, which puts it squarely in European-style 400 V three-phase networks as well.
Thermal curve and real-world loading
This breaker's continuous current is temperature-dependent, and the datasheet gives the full ladder: 60 A at 40 °C, 59 A at 45 °C, 58 A at 50 °C, 56 A at 55 °C, 55 A at 60 °C, 54 A at 65 °C, 53 A at 70 °C. If your panel internal ambient hits 50 °C, you're looking at 58 A continuous — not the 60 A on the label. That matters when the load is a continuous process pump or a compressor bank that runs near the trip threshold. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Power loss is 9.3 W maximum — negligible for panel heat budgeting but worth noting in a sealed enclosure.
Physical fit and panel integration
The 3VA4160-4ED24-0AA0 measures 50.8 mm wide (2 in), 129.4 mm tall (5.09 in), and 75.1 mm deep (2.96 in). That 50.8 mm width is a standard 2-pole MCCB footprint — it occupies two 25 mm module positions on a DIN rail or mounts directly to a backplate via the screw terminals. The IP40 front protection means it's fine inside a closed panel; not for washdown. No trip indicator, no undervoltage release, no ground-fault monitoring — this is a straight thermal-magnetic breaker with no accessories fitted. If your BOM calls for shunt trip or auxiliary contacts, those are add-on modules, not built in.
