Maximum rating is 4800 A, minimum 600 A, with a short-time withstand of 5 kA limited to 1 second. ## Physical fit and auxiliary switches Dimensions are 138 mm wide, 248 mm high, 110 mm deep — that's a 5.43 by 9.76 by 4.33 inch footprint, so check your panel gland plate and DIN-rail spacing before committing. Comes with 2 auxiliary switches (HP design) built in; no auxiliary release fitted, no trip indicator, no voltage trigger.","metaTitle":"Siemens 3VA2440-7HL32-0AB0 SENTRON MCCB, 400 A, 3-Pole, 4800","metaDescription":"Siemens 3VA2440-7HL32-0AB0 SENTRON molded case circuit breaker, 400 A rated, 3-pole, 4800 A max, 330 kA at 240 V.
