Product Positioning
The 3RV2021-0FA15 is an S0-cased motor starting protection circuit breaker in the Siemens SIRIUS 3RV2021 series with a current setting range of 0.35–0.5 A. It comes pre-installed with auxiliary contact modules and is suitable for overload and short-circuit protection of three-phase motor circuits with corresponding current.
Core Product Advantages and Features
Thermo-magnetic composite tripping mechanism
It integrates thermal overload components and electromagnetic instantaneous tripping to reliably cut off the circuit when the current is abnormal at 0.35–0.5 A, protecting the motor and the circuit.
Adjustable current setting
The panel features a current adjustment scale, which can be finely adjusted within the range of 0.35–0.5 A to correspond to the actual rated current of the motor, thereby improving protection accuracy.
Built-in auxiliary contact module
The auxiliary contact module is pre-installed at the factory and can provide NO/NC signal output, which facilitates loop status feedback or linkage control.
