The 3VM1025-3ED42-0AA0 measures 70 mm deep, 101.6 mm wide, and 130 mm tall. The 101.6 mm width — exactly 4 inches — is the standard footprint for a 4-pole SENTRON 3VM frame, so it drops into existing panel cutouts and bus-bar layouts without re-drilling.","metaTitle":"Siemens 3VM1025-3ED42-0AA0 SENTRON MCCB, 4-Pole, 320 A, TM21","metaDescription":"Siemens SENTRON 3VM1025-3ED42-0AA0 molded case circuit breaker, 4-pole, 320 A max, TM210 release. 76 kA at 240 V.
