Three-pole construction, 138 mm wide, 248 mm tall, 110 mm deep — fits standard panel cutouts for 500 A frame MCCBs. Front IP40 protection keeps out tools and finger contact in enclosed switchboards. Max power dissipation is 99 W at rated load; account for that in enclosure thermal calculations, especially in a multi-breaker lineup. The ETU350M overcurrent release provides phase failure detection — critical for motor protection applications where a single-phased condition can burn out a winding before the overload curve catches it. No undervoltage release or shunt trip fitted as standard; the basic switch variant (3VA2450-5MN32-0AA0) is the core breaker without auxiliaries if that's what the BOM calls for. Latching endurance rated at 15,000 operations, which is typical for a 500 A frame used in distribution rather than frequent switching duty.","metaTitle":"Siemens 3VA2450-5MN32-0AC0 SENTRON MCCB, 500 A, 187 kA","metaDescription":"Siemens 3VA2450-5MN32-0AC0 SENTRON molded case circuit breaker, 500 A rated, 187 kA interrupting at 240 V.
