Its 40 A rating holds flat across the full ambient range from 40 °C to 70 °C, so no derating is needed in a warm panel — that is the number to match against your load. Breaking capacity runs from 187 kA at 240 V down to 3.7 kA at 690 V; at the common 415 V level it interrupts 121 kA, giving solid SCCR headroom for most industrial distribution panels. Dimensions are 105 mm wide × 181 mm high × 86 mm deep — the width is the critical number for multi-pole spacing in a distribution board. Front face carries IP40 protection. The ETU320 release is an electronic trip unit with LSI curves (long-time, short-time, instantaneous) — not a thermal-magnetic, so coordination studies need the correct trip-characteristic data. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.","metaTitle":"Siemens 3VA2140-5HL36-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU32","metaDescription":"Siemens SENTRON 3VA2140-5HL36-0AA0 molded case circuit breaker, 40 A continuous, 3-pole, ETU320 release.
