Interrupting capacity is 100 kA at 240 V AC, 65 kA at 480 V AC, and 25 kA at 600 Y/347 V AC. These SCCR figures cover most industrial distribution panels up to 480 V — the 65 kA rating at 480 V is the one that typically governs the bus bracing and upstream transformer impedance. At 600 V corner-grounded delta or wye systems, the 25 kA limit is the binding constraint. Maximum power loss is 29.1 W, which is moderate for a 125 A frame. Panel ventilation and adjacent device spacing should follow the manufacturer's derating guidelines for enclosures above 40 °C. Dimensions are 76.2 mm wide, 129.4 mm high, and 75.1 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount bases in the SENTRON range. The TM210 thermal-magnetic trip unit provides fixed thermal and magnetic settings — no interchangeable rating plugs or electronic adjustments. This simplifies ordering but means the breaker must be sized at the BOM stage for the exact load current; field re-rating is not possible without replacing the entire device.","metaTitle":"Siemens 3VA4112-6ED34-1AA0 SENTRON MCCB, 125 A, 65 kA at 480","metaDescription":"Siemens 3VA4112-6ED34-1AA0 SENTRON 3-pole MCCB, 125 A rated, 65 kA interrupting at 480 V AC.
