Decoding the 3RV2021 4AA10 Datasheet A Comprehensive Guide
The 3RV2021 4AA10 datasheet is much more than just a list of numbers. It’s a comprehensive resource that outlines the capabilities and limitations of this motor starter protector. Understanding the information contained within allows engineers and technicians to properly select, configure, and apply the device in various applications. Essentially, the datasheet allows users to verify that the circuit breaker meets the required protection needs of the motor and the overall system. The ability to correctly interpret this data is paramount to prevent motor damage and ensure operational safety.
The datasheet provides critical parameters such as the current rating, voltage rating, breaking capacity, and tripping characteristics. These specifications dictate the range of motors the 3RV2021 4AA10 can effectively protect. Furthermore, it details the environmental conditions under which the device can operate safely, including temperature and humidity ranges. The datasheet might also contain information about certifications, approvals, and compliance standards, such as UL, CSA, and IEC. Different versions of the 3RV2021 may exist, each with slight variations, so consult the datasheet to ensure it applies to your specific model. Key parameters in the datasheet include:
- Rated Operational Current (Ie)
- Short-Circuit Breaking Capacity (Icu/Ics)
- Adjustable Overload Trip Range
Proper application of the 3RV2021 4AA10 is paramount for safeguarding motors. Ignoring the datasheet recommendations can lead to nuisance tripping, potentially halting operations unnecessarily, or, more seriously, to inadequate protection, resulting in motor burnout or even fire hazards. The datasheet guides you on setting the appropriate overload trip current to match the motor’s full-load amperage (FLA). This adjustment is critical for preventing the circuit breaker from tripping under normal operating conditions while still providing reliable protection against overloads. Different operating characteristics are described, and it is important to match the breaker characteristic with the specific application. This might be visually represented in a table:
| Characteristic | Description |
|---|---|
| A | General Purpose |
| K | High Inrush |
