This is a standard feature on SIRIUS motor-protective breakers, not an option card. The 45 mm width (three module spaces) and 75 mm depth leave room for adjacent contactors and terminals. Any mounting position is allowed. The screw-type terminals for the main circuit accept 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²) solid or stranded — common for motor feeds up to the rated current. Clearance: 20 mm above and below, 9 mm to the side, zero forward and backward.","metaTitle":"Siemens 3RV1011-0KA10-ZW96 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1011-0KA10-ZW96 motor protection circuit breaker, Class 10 trip, 100 kA interrupting at 400 V.
