Interrupting capacity is specified per voltage: 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V. For a 25 A frame, these numbers give generous headroom for selectivity coordination downstream. The unit includes onboard communication capability for integration into a monitoring or control network, and its ground-fault monitoring uses summation current formation on the L + N conductor, so it detects leakage without a separate GFCI module. ## Thermal performance across ambient temperature Storage extremes span -40 °C to 80 °C. Maximum power loss is 0.5 W, negligible for panel thermal budgeting. As a SENTRON-series MCCB, the 3VA2025-7JQ46-0AA0 carries the standard Siemens compliance documentation package: RoHS and REACH declarations, plus the relevant IEC/UL certifications typical for this product class. Specific cert numbers are available with the full datasheet on request.","metaTitle":"Siemens 3VA2025-7JQ46-0AA0 SENTRON MCCB, 25 A, 4-Pole, 330 k","metaDescription":"Siemens SENTRON 3VA2025-7JQ46-0AA0 molded case circuit breaker, 25 A continuous, 4-pole, adjustable thermal range 38-300 A.
