The 3RV2021-4CA10-Z W96 is a Siemens SIRIUS 3RV2 motor protection circuit breaker in the S0 frame size. It is set for a Class 10 overload trip curve with an A-release (thermal overload) adjustable from 16 A to 22 A, and a magnetic short-circuit release (N-release) fixed at 286 A. The screw terminals and standard breaking capacity suit it for fixed-speed motor branch circuits in control panels — typical for pumps, fans, and conveyors where the motor full-load current falls within that 16-22 A window.
