Product Positioning

The 3RV2021-1HA25 is a Siemens SIRIUS 3RV2021 series S0 case motor starting protection circuit breaker with a current setting range of 5.5~8A and built-in 1NO+1NC auxiliary contacts for synchronous feedback of operating status. It is suitable for overload and short circuit protection of three-phase induction motor circuits.

Core Product Advantages and Features
Precise current setting
The thermal overload current can be adjusted by a knob within the range of 5.5~8A to meet the motor's rated current of 8A and reduce the chance of false tripping.
Dual protection mechanism
With dual protection of thermal overload and short-circuit magnetic trip, the power supply can be disconnected immediately in case of motor overload, stall, or phase-to-phase short circuit.
S0 compact housing design
It adopts the SIRIUS 3RV2 series S0 standard housing, which can be directly installed on a 35mm DIN rail. The panel width is only 45mm, saving space in the distribution box.
Auxiliary contact feedback
It has a built-in 1NO+1NC horizontal auxiliary switch, which can simultaneously feed back the tripping or operating status of the circuit breaker to the control circuit or warning lights.
