Interrupting capacity is the headline number here: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. ## Panel fit and wiring constraints The case dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON 3VA2 panel-mounting kits without re-drilling the gland plate. The IP40 front protection is typical for a switchboard interior; keep it behind a locked door or a cover plate. If the BOM calls for a motor drive accessory, this base unit accepts the optional motor drive add-on (Product Extension / Optional / Motor Drive: Yes). For BOM-freeze or compliance documentation, the brand standard for this series includes RoHS, REACH, and IEC/UL certifications as part of the SENTRON release package. Specific declaration files are available on request at quote time.","metaTitle":"Siemens 3VA2025-5HM32-0AA0 SENTRON MCCB, 3-Pole, 25 A, ETU33","metaDescription":"Siemens 3VA2025-5HM32-0AA0 SENTRON molded case circuit breaker, 3-pole, 25 A rated at 40 °C, ETU330 electronic trip unit, 187 kA at 240 V.
