At 415/440 V it still holds 187 kA, which covers the high-fault end of a 400 V industrial distribution. The ETU340 is an electronic trip with an LSI curve: long-time pickup adjustable from 0.4x to 1.0x In (16 A to 40 A), short-time pickup and delay for selective coordination downstream, and instantaneous fixed at 10x In (400 A). That means you can set it to ride through motor inrush and still clear a bolted fault in under 100 ms. ## Physical Fit — DIN Rail or Direct Mount Mounting is via four M6 screws on a backplate or onto a DIN rail adapter (sold separately). Panel builders: plan for 105 mm per pole width plus 5 mm side gap for heat dissipation.","metaTitle":"Siemens 3VA2140-6HK36-0AA0 SENTRON MCCB, 40A 3-Pole ETU340,","metaDescription":"Siemens SENTRON 3VA2140-6HK36-0AA0 molded case circuit breaker. 40A continuous, 3-pole, ETU340 electronic trip.
