The interrupting capacity is 121 kA at 240 VAC and 75.6 kA at 415 VAC — figures that govern its use in high-fault panels where upstream SCCR must be coordinated. The TM210 thermal-magnetic release provides fixed short-circuit pickup at 1250 A (10× Iu), so selectivity with downstream breakers needs to be verified against that threshold. The breaker occupies a 50.8 mm width (2 in) on the DIN rail, with a depth of 70 mm and height of 130 mm. Front IP40 protection means it is suited for enclosed panels where splash or dust ingress is not a concern. The 2-pole footprint matches standard SENTRON 3VA spacing, so a panel originally laid out for a 3VA1112-5EE32-0AA0 will accept this unit without rewiring — same mounting centers, same bus-bar pitch. Above that, derate linearly: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. Maximum power dissipation is 18.74 W at rated load — a figure to include in enclosure thermal calculations.","metaTitle":"Siemens 3VA1112-4ED26-0AA0 SENTRON MCCB, 2-pole, 125 A, 121","metaDescription":"Siemens SENTRON 3VA1112-4ED26-0AA0 molded case circuit breaker, 2-pole, 125 A, 121 kA at 240 VAC.
