The interrupting ratings tell you where this breaker fits: 187 kA at 240 V AC, 121 kA at 415 V, 55 kA at 440 V, 36 kA at 500 V, and 7.5 kA at 690 V — so at typical 400 V class distribution voltages it handles high fault currents without cascading upstream. The ETU350 release gives adjustable short-time delay (tsd) from 0.02 s to 0.4 s and adjustable response time (tr) from 0.5 to 17 s, which lets you coordinate selectively with downstream breakers on a feeder or main. Thermal derating is published: the breaker holds 400 A through 50 °C, then drops to 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C. Dimensions: 138 mm wide (5.4 in), 248 mm high (9.8 in), 110 mm deep. The 110 mm depth includes the case body; verify clearance for the ETU wiring and any auxiliary contact blocks behind the front cover.","metaTitle":"Siemens 3VA2340-5HN32-0KG0 SENTRON MCCB, 400 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2340-5HN32-0KG0 molded case circuit breaker, 400 A continuous, 3-pole, ETU350 release, 187 kA at 240 V.
