ABB TA25 DU 32 thermal overload relay

The ABB TA25 DU 32 is a thermal overload relay. Here is a brief description of some of the main features and specifications of this relay:

Brand and Model: This relay is produced by ABB company, model number TA25 DU 32.ABB is a world-renowned power and automation technology company, and its products enjoy a wide reputation in the electrical industry.

Application: The relay is mainly used for thermal or thermal overload protection. In the circuit, when the current exceeds the set value, the relay will operate, disconnecting the circuit, thus protecting the device from damage.

Contact load and form: The TA25 DU 32 has a medium power contact load, and the contact form is one open and one closed. This design enables it to be adapted to a wide range of applications.

Rated current and voltage: The rated current of the relay is 32A and the rated voltage is 220V. This means that it can work steadily and reliably within the rating range.

Protection features and coil power supply: The relay has an open protection feature and the coil power supply is a single power supply. These characteristics help ensure the safe and stable operation of the relay.

ABB's TA25 DU 32 thermal overload relay is used as a protection device for the following circuit equipment:

Motor protection: The most common application of thermal overload relays is to protect motors from thermal overload. When the motor runs for a long time or is overloaded, the current will increase, causing the motor to heat up. Thermal overload relay by monitoring the size of the current, when the current exceeds the preset value, it will trigger the relay action, disconnect the motor power, so as to prevent the motor from overheating damage.

Circuit control and protection: In addition to motors, thermal overload relays can also be used to control and protect other circuit equipment. It can monitor the current in the circuit, and once the current exceeds the safe range, the relay will operate, disconnect the circuit, and protect other equipment from damage.

Industrial equipment: In the industrial sector, many equipment need to operate for a long time and withstand high loads. These devices are usually equipped with thermal overload relays to ensure that the equipment can be safely shut down in case of overload or abnormal conditions, preventing equipment damage or accidents.

Automation equipment and control systems: In automated production lines and control systems, thermal overload relays are often used to monitor and control the working status of circuits. When the current in the circuit exceeds the normal range, the relay can automatically cut off the power to prevent equipment failure or system crash.
