3RV2021-1CA15
The 3RV2021-1CA15 is a SIRIUS 3RV2021 series S0 frame motor protection circuit breaker. It has a current adjustment range of 1.8–2.5A, thermal and electromagnetic double tripping, easy dial setting, and a built-in 1NO+1NC signal contact for direct feedback of operating status. It is suitable for motor control panels and production line power distribution circuits.
Product Positioning
As a member of the SIRIUS 3RV2021 series, the 3RV2021-1CA15 is an S0 frame motor protection circuit breaker with a current setting range of 1.8–2.5A. The overload action point can be quickly set by rotating the dial, and it is combined with an electromagnetic short-circuit tripping mechanism, making it suitable for motor control panel opening and closing circuits.
Core Product Advantages and Features
Dual protection against overload and short circuit
It uses a thermal heating element to detect overload current and also has an electromagnetic tripping mechanism to deal with instantaneous short circuits. The two protection mechanisms work in tandem.
quick dial calibration on site
The overload action point can be set by rotating the dial and comparing it with the motor nameplate current, allowing for on-site calibration without tools.
Built-in 1NO+1NC signal contacts
The circuit breaker has one set of normally open and one set of normally closed auxiliary contacts built into the main body, and the circuit breaker's operating status can be directly fed back to the control circuit, eliminating the need for additional wiring.
Support for collective motor installation applications
Suitable as an on/off/isolation element in a collective motor mounting architecture, it is easy to integrate into existing switchboard configurations.
