Ground fault detection is not included, so if that is required, an external ground-fault module or relay must be added. The 55 mm width and 140 mm height are standard for this SIRIUS frame size; depth of 149 mm leaves clearance for the screw-type box terminals on the main circuit and the auxiliary contact block on top. Zero clearance required at the back or sides, so adjacent devices can butt directly against it — no derating for side-by-side packing in a crowded panel. The auxiliary and control circuit also uses screw terminals. Terminal capacity is generous for the 40 A rating — no need to pigtail down to a smaller wire.","metaTitle":"Siemens 3RV1031-4FA10-0BA0 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1031-4FA10-0BA0 SIRIUS motor protection circuit breaker, 40 A continuous, CLASS 10 trip, 50 kA at 400 V.
