Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 76 kA at 500 V, and 17 kA at 690 V — figures that let it ride through high-fault scenarios typical of industrial distribution without cascading upstream. The ETU340 electronic trip unit provides adjustable N-conductor protection (OFF or 100%) and a fixed long-time delay (tr) of 1300 ms, giving selectivity headroom for downstream feeders. The 3VA2140-5HK42-0AA0 measures 86 mm deep, 140 mm wide, and 181 mm tall — a 4-pole footprint that fits standard SENTRON panel cutouts and busbar systems. ## Mechanical endurance and storage Latching endurance is 20,000 cycles.","metaTitle":"Siemens 3VA2140-5HK42-0AA0 SENTRON MCCB, 40 A, 4-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2140-5HK42-0AA0 molded case circuit breaker, 40 A, 4-pole, 187 kA at 240 V.
