It carries a 242 kA interrupting capacity at 240 V, dropping to 187 kA at 415 V and 440 V, then to 121 kA at 500 V, and 9 kA at 690 V — a curve that tells you this breaker is built for high-fault low-voltage distribution, not for 690 V motor feeders where the available fault current stays under 9 kA. The breaker measures 248 mm high, 138 mm wide, and 110 mm deep — a 3-pole frame that fits standard Siemens 3VA2 switchboard mounting patterns. The 110 mm depth (4.33 in) is shallow enough for most 400 mm deep enclosures, but verify busbar clearance behind the breaker if the panel uses rear-connected risers. No DIN-rail mounting; this is a bolted-frame MCCB for fixed or plug-in base installation.","metaTitle":"Siemens 3VA2450-6HK32-0AA0 SENTRON MCCB, 500 A, 242 kA at 24","metaDescription":"Siemens 3VA2450-6HK32-0AA0 SENTRON molded case circuit breaker, 500 A, 3-pole, ETU340 release, 242 kA at 240 V.
