The Siemens 3VA1116-5ED32-0AH0 is a SENTRON molded case circuit breaker (MCCB) in a 3-pole configuration, fitted with a TM210 thermal-magnetic release and rated for line-protection duty. The TM210 designation means the continuous current rating is 160 A, and it holds that full rating from 40 °C up through 50 °C ambient; above that it derates to 158 A at 55 °C and 150 A at 70 °C — a curve to check if your panel runs hot. Breaking capacity ranges from 187 kA at 240 V down to 17 kA at 500/690 V, so the available fault current at your service voltage determines whether this frame clears the fault without upstream coordination issues.
Key ratings and what they mean for fit
Rated insulation voltage is 800 V, so the breaker is suitable for 480/600 V class systems with margin. Power loss at full load is 38 W maximum — that's the heat to vent inside the enclosure; if you're packing multiple breakers in a small panel, the cumulative dissipation matters for the cooling calculation. The auxiliary switch block comes with 2 auxiliary switches plus 1 trip alarm switch (HQ type), covering status feedback and alarm annunciation without adding a separate accessory. A mechanical trip indicator is present on the front — useful for a quick visual walk-down during troubleshooting.
Physical integration
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep. The 3-pole frame mounts onto a DIN rail or panel baseplate; the 70 mm depth keeps it within standard enclosure depths for distribution boards. No undervoltage release or communication module fitted from the factory, so if those are needed they must be added as separate accessories.
