If the panel sits near a heat source or in a non-ventilated cabinet, size the load at the derated figure — the TM210 release responds to both thermal (overload) and magnetic (short-circuit) elements, and running at full 125 A in a 70 °C ambient risks nuisance tripping. Maximum power dissipation is 9.37 W, negligible for most DIN-rail layouts but worth tallying in a densely packed enclosure. The breaker occupies a single 25.4 mm (1 in) width slot on DIN rail, with a depth of 70 mm and height of 130 mm. That 25.4 mm pole pitch is standard for SENTRON 3VA components — it drops into the same rail space as other 1-pole 3VA breakers, so swapping between variants (e.g., different trip ratings or interrupting capacities) does not require re-drilling the backplate or re-routing busbars. Front IP40 protection keeps tools and fingers out but is not rated for washdown; keep it behind a panel door in wet environments. ## Operating environment and storage The storage range exceeds the operating range — that governs handling during shipping and site idle periods, not running conditions. Insulation voltage is rated 500 V, so the 415 V AC / 125 V DC operating voltages sit well within the dielectric margin.","metaTitle":"Siemens 3VA1112-3ED16-0AA0 SENTRON MCCB, 1-pole, 125 A, 52.5","metaDescription":"Siemens SENTRON 3VA1112-3ED16-0AA0 molded case circuit breaker, 1-pole, 125 A rated at 40 °C, TM210 release, 52.5 kA interrupting at 240 V.
