The Siemens 3VA4112-6ED34-0AA0 is a 3-pole SENTRON molded-case circuit breaker rated 125 A at 40 °C, with a TM210 thermal-magnetic release designed for system protection — meaning it handles distribution feeder duty, not motor-starting curves. That 65 kA at 480 Y/277 V tells you it's rated for wye-grounded systems common in North American commercial panels. Thermal derating is published across the full range: 125 A at 40 °C, 120 A at 50 °C, 115 A at 60 °C, 109 A at 70 °C. Dimensions are 75.1 mm deep, 76.2 mm wide, 129.4 mm high — a standard 3-pole MCCB footprint that drops onto DIN rail or direct-mount busbars.
