The electronic trip unit ETU320 provides adjustable overload and short-circuit protection, covering a current setting range from 60 A to 480 A. Breaking capacity is specified across multiple voltage levels: 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The breaker measures 86 mm deep, 140 mm wide, and 181 mm high. It mounts on a DIN rail or directly in a panel enclosure; the 4-pole width (140 mm) matches the standard SENTRON 4-pole footprint, so it slots into existing MCCB layouts without re-drilling gland plates. ## Thermal performance and installation notes Continuous current rating holds at 40 A across the full ambient temperature range from 40 °C to 70 °C (–). That means no derating is needed in warm enclosures — the breaker delivers its full 40 A even at 70 °C ambient. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Front protection class is IP40 — suitable for general indoor panel use, not washdown environments.","metaTitle":"Siemens 3VA2140-7HL46-0AA0 SENTRON MCCB, 4P, 40A, ETU320, 33","metaDescription":"Siemens SENTRON 3VA2140-7HL46-0AA0 molded case circuit breaker, 4-pole, 40 A continuous, ETU320 release, breaking capacity 330 kA at 240 V AC.
