TB850 ABB
The TB850 is a product manufactured by ABB, a leading multinational company that specializes in electrification and automation technologies. This product is a compact and efficient thermal overload relay that is designed to protect motors and other electrical equipment from damage caused by overloading or phase failure.
The TB850 is equipped with a number of parameters that can be adjusted to suit different applications and requirements. These parameters include:
- Current setting range: The TB850 can be set to trip at a specific current range, ranging from 0.1 to 63 A.
- Trip class: The TB850 can be set to operate in different trip classes, depending on the level of protection required. The available trip classes are:
- Class 10: For applications where moderate levels of overload protection are required.
- Class 20: For applications where high levels of overload protection are required.
- Class 30: For applications where very high levels of overload protection are required.
- Manual or automatic reset: The TB850 can be set to either manual or automatic reset. In manual reset mode, the relay must be manually reset after a trip. In automatic reset mode, the relay will automatically reset after a trip once the overload or phase failure has been corrected.
- Phase failure protection: The TB850 can be set to protect against phase failure, which is a common cause of motor damage. This feature detects any phase loss and will trip the relay to protect the motor.
In addition to these parameters, the TB850 also has a number of product information specifications that are important to consider when selecting and using the product. These specifications include:
- Rated insulation voltage: The TB850 has a rated insulation voltage of 690 V AC, which is the maximum voltage at which the product can operate safely.
- Rated operational voltage: The TB850 has a rated operational voltage of 690 V AC, which is the maximum voltage at which the product can operate continuously.
- Mounting type: The TB850 can be mounted on a standard DIN rail, making it easy to install and remove.
- Ambient temperature range: The TB850 can operate within an ambient temperature range of -25°C to +55°C, making it suitable for use in a wide range of environments.
- Protection degree: The TB850 has a protection degree of IP20, which means that it is protected against solid objects greater than 12 mm in diameter, but is not protected against the ingress of water.
Overall, the TB850 is a reliable and versatile thermal overload relay that provides excellent protection for motors and other electrical equipment. By adjusting the various parameters and considering the product information specifications, users can ensure that the TB850 is optimized for their specific application.
