Ground fault detection is not included, so if that's required you'd add a separate ground-fault module downstream. Breaking capacity hits 100 kA at 240 V and 400 V AC, drops to 3 kA at 500 V, and 2 kA at 690 V. The 690 V rating (2 kA) covers 600 V class North American systems and 690 V European drives. The surge voltage withstand is 6 000 V, which aligns with IEC 60947-2 overvoltage category III for fixed installations. ## Termination and mounting Both the main current circuit and auxiliary/control circuit use spring-loaded terminals — no screwdriver needed for the wire, just strip and push. Main contacts accept 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with ferrule. AWG equivalent is 2x (24... 14). Width is 45 mm, height 90 mm, depth 81 mm. The IP20 front face is finger-safe — touch protection against accidental contact with live parts during panel access.","metaTitle":"Siemens 3RV1011-1EA20-ZW95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1011-1EA20-ZW95 SIRIUS motor protection circuit breaker, 4 A, CLASS 10 trip, 100 kA at 400 V, spring terminals, 45 mm wide.
