Breaking capacity runs 100 kA at 240 V AC, 50 kA at 400 V AC, 10 kA at 500 V AC, and 4 kA at 690 V AC (–). The 55 mm width and 140 mm height leave room for adjacent contactors or overloads in a motor starter lineup. Screw-type box terminals on the main circuit accept 2x (0.75–16 mm²) solid or 2x (0.75–25 mm²) stranded, with a single termination up to 35 mm². That's enough for 40 A motor feeds with standard THHN or PVC cable. Auxiliary and control circuits also use screw terminals, and the breaker accepts an auxiliary switch add-on.","metaTitle":"Siemens 3RV1031-4FA10-ZW98 SIRIUS Motor Protection CB, 40 A,","metaDescription":"Siemens 3RV1031-4FA10-ZW98 SIRIUS circuit breaker for motor protection, 40 A continuous, 18.5 kW at 400 V, Class 10 trip, 50 kA breaking capacity.
