Its interrupting capacity reaches 187 kA at 240 V and 121 kA at 415 V — figures that cover high-fault utility feeds and transformer secondaries without cascading upstream. Rated insulation voltage Ui is 800 V, so it handles 480 V and 600 V class systems with full coordination margin. The 187 kA at 240 V and 121 kA at 415 V are the short-circuit current ratings (SCCR) the breaker can safely interrupt at those voltages. In a 480 V panel fed from a 1000 kVA transformer, the available fault current often exceeds 65 kA — this breaker clears it without rupturing. The 125 A continuous rating holds flat to 50 °C; above that, the thermal curve derates 2.5 A per 5 °C step. The TM210 release means the thermal element is fixed at 125 A (not adjustable), while the magnetic pickup is factory-set to 10× In (1250 A). The UVR order code is 3VA9608-0BB25. Dimensions: 130 mm height, 76.2 mm width, 70 mm depth. Operating temperature range -25 °C to 70 °C; storage from -40 °C to 80 °C. No communication module, no phase-failure detection, no voltage trigger — this is a pure line-protection breaker with undervoltage release only.","metaTitle":"Siemens 3VA1112-5ED32-0DA0 SENTRON MCCB, 125 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1112-5ED32-0DA0 molded case circuit breaker. 125 A rated, 3-pole, line protection, TM210 release. 187 kA at 240 V, 121 kA at 415 V.
