The Siemens 3VA1116-6FE46-0AA0 is a SENTRON 3VA1 molded case circuit breaker rated for 80 A continuous, 4-pole, with a TM220 thermal-magnetic release. The TM220 release gives a fixed thermal curve and fixed magnetic trip, no adjustment dials, so what you order is what you get for coordination studies.
Breaking capacity — the real selectivity number
This breaker delivers 220 kA interrupting capacity at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. The 17 kA at 690 V still covers most industrial distribution.
Thermal derating — don't size by the 80 A alone
At 55 °C it derates to 158 A, at 65 °C to 153 A, and at 70 °C to 150 A.
That 101.6 mm width is exactly 4 inches — a standard MCCB frame width for a 4-pole unit, meaning it fits the common panel cutout and bus-bar spacing used across the SENTRON 3VA line.
What it does not include
This variant has no undervoltage release, no trip indicator, no voltage trigger, no communication function, and no ground-fault monitoring. It is a straight thermal-magnetic line-protection breaker — no auxiliaries, no remote trip, no metering. If the BOM calls for those, you need a different suffix in the 3VA1 family.
