Interrupting capacity is 75.6 kA at 240 V AC and 52.5 kA at 415 V AC — figures that cover most industrial service-entrance and feeder applications. The thermal derating curve is published: 125 A from 40 °C through 50 °C, then 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. Maximum power loss is 18.74 W. In a dense panel with multiple breakers side by side, that heat adds to the internal ambient and accelerates the derating effect — something to check if you are packing several 125 A frames into a small enclosure. The 3VA1112-3ED22-0AA0 measures 70 mm deep, 50.8 mm wide (2 inches), and 130 mm high. The 2-inch width per pole is standard for SENTRON 3VA frames, so it occupies one 2-pole module on the DIN rail or panel-mount footprint. Front face carries an IP40 protection class — splash protection is not provided, so the breaker belongs in a closed cabinet, not in a washdown zone. No trip indicator, no undervoltage release, no communication function on this variant — it is a straight thermal-magnetic breaker with no auxiliary electronics.","metaTitle":"Siemens 3VA1112-3ED22-0AA0 SENTRON MCCB, 125A, 2-Pole, TM210","metaDescription":"Siemens 3VA1112-3ED22-0AA0 SENTRON molded case circuit breaker, 125A at 40°C, 2-pole, TM210 release, 75.6kA at 240V.
