The TeSys Deca frame 3 motor circuit breakers, previously known as TeSys GV3, are designed to offer comprehensive protection for motors up to 80 A (45 kW / 400 V). Here are their key features:

1. Motor Protection: These circuit breakers are specifically engineered to safeguard motors against overloads and short circuits. By detecting abnormal conditions in the electrical circuit, they help prevent damage to motors and associated equipment.
2. Coordination with TeSys Deca Contactors: The circuit breakers are coordinated with TeSys Deca contactors, ensuring seamless integration and optimal performance within motor control systems. This coordination enhances system reliability and efficiency.
3. Manual Control and Isolation: They feature manual control and isolation functionalities, allowing operators to manually start, stop, and isolate the motor from the power supply. This enhances safety during maintenance, servicing, and troubleshooting activities.
4. Wide Housing: The circuit breakers are housed in a 55 mm wide enclosure, providing ample space for internal components and facilitating installation in electrical panels and enclosures. The wider housing accommodates additional features and enhances durability.
5. Comprehensive Protection: TeSys Deca frame 3 circuit breakers offer both overload and short-circuit protections, ensuring comprehensive protection for motors in industrial applications. This ensures reliable operation and extends the lifespan of motors and associated equipment.

Overall, TeSys Deca frame 3 motor circuit breakers, formerly known as TeSys GV3, provide robust and efficient protection for motors up to 80 A. With their comprehensive features and coordinated operation with TeSys Deca contactors, they offer an integrated solution for motor control and protection in industrial environments.
