Dimensions are 97 mm deep, 45 mm wide, and 97 mm tall, with 50 mm clearance needed above and below, 30 mm to the side, and zero clearance forward or backward. Main circuit terminals accept 2x 1 to 2.5 mm² or 2x 2.5 to 10 mm² solid or stranded wire, with M4 screw terminals for the main contacts.","metaTitle":"Siemens 3RV2021-1FA10-ZW96 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV2021-1FA10-ZW96 SIRIUS motor protection circuit breaker.
