The integrated auxiliary trip module is order code 3VA9608-0BB11; the supplied basic switch is 3VA2340-5HL42-0AA0. Mechanical endurance is 15,000 operations. ## Physical fit and environmental range Dimensions are 248 mm high, 184 mm wide, 110 mm deep — standard SENTRON 3VA2 footprint for a 400 A frame. No trip indicator on this variant, no voltage trigger. Ground fault monitoring is not fitted. The breaker mounts in a standard distribution panel or switchboard — no DIN-rail clip on this frame size, it bolts in.","metaTitle":"Siemens 3VA2340-5HL42-0BC0 SENTRON MCCB, 400 A, 4-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2340-5HL42-0BC0 molded case circuit breaker, 400 A, 4-pole, 187 kA at 240 V.
