The interrupting rating drops to 121 kA at 415 V and 75.6 kA at 440 V, so verify your system voltage against the curve before committing the BOM line. The 125 A rating holds flat from 40 °C through 50 °C, then derates to 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. That means you can remote-trip the breaker from a safety circuit or E-stop string, and the auxiliary contacts report breaker position back to the PLC or SCADA. No undervoltage release fitted — if you need UVR, this order code isn't it. ## Lifecycle and compliance — current production, no obsolescence concern No DIN-rail mounting on this class; it's screw-fixed to a backplate or busbar system.","metaTitle":"Siemens 3VA1112-5ED32-0KH0 SENTRON MCCB, 125A, 3-Pole, 187kA","metaDescription":"Siemens 3VA1112-5ED32-0KH0 SENTRON molded case circuit breaker, 125A, 3-pole, 187kA interrupting at 240V.

The difference is in the trip rating and accessories — this one is 125 A with a shunt trip and HQ aux switch configuration, while the 3VA1110-5EF32-0AM0 is a different amp rating and accessory set. Verify the trip curve and aux wiring against your panel schematic before swapping."},{"question":"What compliance documentation does this brand provide for 3VA1112-5ED32-0KH0?","answer":"Siemens SENTRON MCCBs carry UL, CSA, and IEC certifications as standard.
