Motor Protection Circuit Breaker — SIRIUS 3RV1021-4CA10-0FJ0-ZX95
No ground fault detection on this variant — that's a separate function.
Breaking Capacity and Voltage Ratings
Breaking capacity at 240 V AC is 100 kA, at 400 V AC it's 50 kA, at 500 V AC it's 10 kA, and at 690 V AC it's 4 kA. Surge voltage resistance rated value is 6 000 V, which covers the impulse withstand requirements for industrial environments per IEC 60947-2.
Width is 45 mm, height 97 mm, depth 96 mm — a standard 45 mm module that fits alongside contactors and overloads in a motor starter row. Terminals are screw-type for the main current circuit. Solid and stranded conductors: 2x (1... 2.5 mm²) and 2x (2.5... 6 mm²). AWG equivalents for main contacts: 2x (14... 10). Finely stranded with core end processing also accepts 2x (1... 2.5 mm²) and 2x (2.5... 6 mm²). That covers the common panel wire sizes for a 22 A circuit. Shock resistance is 25g / 11 ms.
Power dissipation at AC in hot operating state is 10.5 W total, 3.5 W per pole. Mechanical endurance of the main contacts is 100 000 operations typical. Maximum switching rate at AC-3 is 15 cycles per hour.
