It carries a TM210 thermal-magnetic overcurrent release — fixed thermal, adjustable magnetic — with an li max setting up to 320 A for short-circuit pickup. Breaking capacity scales with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V and 690 V. That spread covers most industrial distribution panels — the 415 V figure is the one to check for European 400 VAC networks. Rated insulation voltage Ui is 800 V, and the maximum rated operational voltage for DC applications is 500 V. The breaker is rated for 25 A continuously up to 50 °C ambient; above that it derates linearly to 23 A at 70 °C. ## What the ratings mean for panel fit At 70 mm deep by 76.2 mm wide by 130 mm tall, this 3-pole MCCB fits the standard SENTRON 3VA1 footprint — same base dimensions across the 25 A frame. It mounts on a DIN rail or panel, and the front face carries an IP40 protection rating, adequate for enclosed distribution boards but not for washdown environments. Maximum power loss is 8.5 W at rated current — negligible for thermal budgeting inside a panel, but worth noting if you're packing multiple breakers in a small enclosure with limited ventilation. Operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C. The storage limits govern handling and shipping, not running conditions. ## Lifecycle and sourcing reality The 3VA1125-3ED32-0AA0 is a standard SENTRON molded case circuit breaker with no communication function and no ground-fault monitoring version. It is available with an optional motor drive for remote operation.","metaTitle":"Siemens 3VA1125-3ED32-0AA0 SENTRON MCCB, 25 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1125-3ED32-0AA0 molded case circuit breaker, 25 A, 3-pole, TM210 release, 75.6 kA at 240 V.
