Decoding the 3RV2011 1EA10 Datasheet Motor Protection
The 3RV2011 1EA10 is a compact circuit breaker designed primarily for protecting electric motors from overload and short-circuit conditions. It’s often referred to as a motor starter protector or a manual motor starter, though technically it’s a circuit breaker. Its main job is to disconnect the motor from the power supply if it detects a fault, preventing damage to the motor and other components in the system. Unlike simple fuses, the 3RV2011 1EA10 can be reset after tripping, allowing for quick restoration of operation after the fault has been cleared. It offers adjustable current settings, enabling it to be precisely matched to the motor’s full-load amperage, ensuring optimal protection without nuisance tripping.
The datasheet details the 3RV2011 1EA10’s technical specifications, including its current rating, voltage rating, breaking capacity, and trip class. It also outlines its compliance with various industry standards, such as IEC and UL certifications. Understanding these ratings is crucial for ensuring the breaker is suitable for the intended application. For example, the breaking capacity indicates the maximum fault current the breaker can safely interrupt. Exceeding this value can lead to catastrophic failure. The trip class determines the breaker’s response time to overload conditions; different classes are suitable for motors with varying starting characteristics. Some important data points found on the datasheet include:
- Current range (adjustable)
- Voltage rating
- Breaking capacity
- Trip class
- Ambient temperature range
The 3RV2011 1EA10 is widely used across diverse industrial applications, protecting motors in pumps, fans, compressors, conveyors, and other machinery. Its compact size and reliable performance make it a popular choice for control panels and motor control centers (MCCs). Correct selection and installation, guided by the datasheet, are essential for ensuring the longevity and efficient operation of the protected motor. Here’s a simplified table illustrating potential applications:
| Application | Why 3RV2011 1EA10 is suitable |
|---|---|
| Pumps | Protects against overload during pump operation. |
| Fans | Safeguards against motor failure due to fan blade obstruction. |
| Conveyors | Prevents damage from jammed conveyors causing motor strain. |
