The 138 mm width is a 3-pole frame; it fits standard SENTRON 3VA switchboard cutouts and DIN-rail adapters. The basic switch element is order code 3VA2450-5MN32-0AA0; the integrated auxiliary trip is 3VA9688-0BL30 — both are serviceable spares if you need to replace just the trip unit or the switch mechanism.","metaTitle":"Siemens SENTRON 3VA2450-5MN32-0HA0 MCCB, 500 A, Motor Protec","metaDescription":"Siemens SENTRON 3VA2450-5MN32-0HA0 molded case circuit breaker, 500 A rated current, motor protection with ETU350M trip unit, shunt trip.
