That 40 A hold at 70 °C is unusual for an MCCB; most competitors start pulling current back above 40 °C. The interrupting capacity tells the real story: 242 kA at 240 V, 187 kA at 415 V, and still 121 kA at 500 V. The 3VA2140-6HL36-0AA0 measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint for a 160 A frame. The 1.6 W maximum power loss is low enough that ventilation spacing in a typical panel won't need rethinking. ## Trip unit and release options The overcurrent release is an ETU320 — an electronic trip unit with fixed thermal and magnetic settings, no communication function, no voltage trigger, and no undervoltage release. No ground-fault monitoring version is fitted. The motor drive option is available as an extension, meaning remote charging or closing can be added later without swapping the breaker.","metaTitle":"Siemens 3VA2140-6HL36-0AA0 SENTRON MCCB, 40 A, 242 kA at 240","metaDescription":"Siemens SENTRON 3VA2140-6HL36-0AA0 molded case circuit breaker, 3-pole, 40 A rated, 242 kA interrupting at 240 V.
