Rated insulation voltage is 800 V, and the breaker operates across -25 °C to 70 °C ambient, with storage from -40 °C to 80 °C. ## Mounting Dimensions and Panel Fit The 140 mm width across four poles is standard for a 4-pole MCCB in this frame size — verify the DIN-rail or bolt-on mounting footprint matches the existing backpanel layout. No undervoltage release or communication module is fitted on this variant, so no additional wiring for those accessories is needed.","metaTitle":"Siemens 3VA2025-7HN46-0AA0 SENTRON MCCB, 25 A, 4-Pole, ETU35","metaDescription":"Siemens SENTRON 3VA2025-7HN46-0AA0 molded case circuit breaker, 25 A continuous, 4-pole, ETU350 trip unit. 330 kA at 240 V.
