At 415 V — common for industrial three-phase distribution in Europe and Asia — the 121 kA figure gives you serious fault-current headroom for a 40 A frame. The 690 V rating is low enough that you'd check selectivity carefully if that's your system voltage. ## Thermal derating and ambient That's unusual for an MCCB; most frames start dropping current above 40 °C. Dimensions are 181 mm high × 140 mm wide × 86 mm deep (7.13 × 5.51 × 3.39 inches), which fits the standard SENTRON 3VA mounting footprint.","metaTitle":"Siemens 3VA2140-5HL46-0AA0 SENTRON MCCB, 40 A, 4-Pole, ETU32","metaDescription":"Siemens SENTRON 3VA2140-5HL46-0AA0 molded case circuit breaker, 40 A continuous, 4-pole, ETU320 release.
