The 3RV2011 1DA10 datasheet is your comprehensive guide to understanding and utilizing a crucial component in motor protection: a specific type of circuit breaker designed for motor starter applications. This document provides all the necessary technical specifications, performance characteristics, and application guidelines for the 3RV2011 1DA10, ensuring proper selection and integration of this device into your electrical systems. Without the 3RV2011 1DA10 datasheet, engineers and technicians would struggle to accurately apply and maintain this motor starter protector. Therefore, it is critical for ensuring the safe and efficient operation of motors.
Decoding the 3RV2011 1DA10: What It Is and How It’s Used
The 3RV2011 1DA10, detailed within its datasheet, is essentially a compact circuit breaker designed specifically for protecting motors from overload and short-circuit conditions. Unlike general-purpose circuit breakers, the 3RV2011 1DA10 is optimized to handle the unique starting characteristics of motors, such as the inrush current. This inrush current, a temporary surge of current drawn by the motor during startup, can trip standard circuit breakers prematurely. The 3RV2011 1DA10’s design incorporates a time-delay mechanism that allows it to withstand this inrush current without tripping, while still providing reliable protection against sustained overloads. Here are the key functions it provides:
- Overload protection
- Short-circuit protection
- Phase failure protection
The application of the 3RV2011 1DA10 is commonly found in motor starter combinations, where it works in conjunction with contactors and overload relays to provide comprehensive motor protection. The 3RV2011 1DA10 acts as the primary circuit breaker, protecting against short circuits and providing a means of disconnecting the motor for maintenance. Overload relays, on the other hand, are designed to protect the motor from sustained overloads that could cause overheating and damage. By coordinating these protective devices, engineers can ensure the long-term reliability of their motor-driven equipment. Below is a example when this device can be used:
- HVAC systems
- Pumps
- Conveyors
Understanding the specifications outlined in the 3RV2011 1DA10 datasheet is crucial for selecting the correct device for a given motor. Key parameters include the rated current, which must be matched to the motor’s full-load current, and the breaking capacity, which indicates the device’s ability to interrupt a short-circuit current. The datasheet also provides information on trip curves, which define the relationship between current and tripping time. Here is a simple table for understanding some of the key parameters:
| Parameter | Description |
|---|---|
| Rated Current | Maximum current the device can handle continuously. |
| Breaking Capacity | Maximum short-circuit current the device can interrupt safely. |
