The Siemens 3VM1196-3EE46-0AA2 is a SENTRON molded case circuit breaker (MCCB) rated for 16 A continuous current at 40 °C, with a 4-pole configuration and a TM220 thermal-magnetic release. The frame is sized for up to 160 A, so this 16 A unit leaves headroom for future load growth if you swap the trip unit.
The interrupting ratings drop as voltage rises: 76 kA at 240 V, 53 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V AC. At 500 V DC the maximum rated operational voltage is 500 V. That 11.9 kA at 500 V AC is the number to check if you're feeding a 480 V panel — it's still adequate for most North American 480Y/277 V services, but verify your available fault current.
At 60 °C it derates to 15 A, and it stays at 15 A through 70 °C. That derating curve is flat enough that you don't need to oversize for a warm panel — just watch the 60 °C threshold.
Front-connected box terminals accept copper or aluminum conductors. No auxiliary contacts are fitted as standard (0 CO contacts), so if you need alarm or trip indication, plan for an external auxiliary switch module.
