The GV2ME06 is a compact electrical device that integrates isolation, protection, and control. It is primarily designed to provide comprehensive protection for three-phase asynchronous motors and is a very common and critical component in industrial automation control circuits.
Brand: Schneider Electric
Series: TeSys GV2
Model: GV2ME06
Key Features: Compact design, comprehensive functionality, safety and reliability, and easy installation.
2. Main Functions and Features
Core Protection Functions:
Short-circuit protection: This is achieved through an electromagnetic release. When a sudden high-current short circuit occurs, it quickly (instantaneously) disconnects the circuit, protecting the motor and subsequent wiring from damage.
Overload protection: This is achieved through a thermal release. If a motor is operated at a current exceeding the rated current for a prolonged period, it will overheat and burn out. The GV2ME06's thermal element simulates the motor's thermal characteristics. When the overload current persists for a certain period, it will trigger a delayed trip to disconnect the power supply.
Phase loss protection: This is also a key function of the thermal-magnetic protection mechanism. When one phase of a three-phase power supply is missing, the motor's current increases dramatically, leading to overheating. The GV2ME06 detects this imbalance and trips to protect the motor.
Control and Isolation Functions:
Isolation Function: It features a clearly visible disconnect point, meeting safety standards for isolating electrical devices. During motor maintenance and repair, it can be disconnected to isolate the power supply and ensure personnel safety.
Control Function: It functions as a switch, allowing you to start and stop the motor directly. It can also be remotely controlled by operating its trip mechanism via an external button.
Other Features:
Current Adjustment Range: The GV2ME06's rated current is adjustable. Its set current range is typically 0.4A to 0.63A. You can precisely set the current within this range based on the actual rated current of the protected motor, ensuring accurate protection.
Auxiliary Contacts: It can be equipped with an auxiliary contact module to transmit the circuit breaker's status (e.g., closed, open, or fault trip) to a PLC or other control system for status monitoring and alarming.
Trip Indicator: Features a red trip indicator. When the circuit breaker trips due to an overload or short circuit, the indicator pops up, allowing the operator to quickly identify the fault type (it can also distinguish between overload and short circuit with auxiliary contacts).
Easy Installation: Can be mounted on a DIN rail (such as a 35mm standard rail), making installation and removal very convenient.

4. Model Nomenclature
GV2: Schneider's motor circuit breaker series.
M: Standard type.
E: Knob-operated.
06: Frame size. Within this series, 06 typically corresponds to a lower current rating. The GV2 series also offers higher current ratings, such as the GV2P (08, 10, 14, 16, and 20).
5. Typical Applications
The GV2ME06 is widely used in various applications requiring protection of small three-phase motors, such as:
Machine tools
Conveyor systems
Fans and pumps
Compressors
Packaging machinery
Automated production lines
The GV2ME06 is a reliable, cost-effective micro motor protection circuit breaker. It integrates the short-circuit protection of a circuit breaker, the overload protection of a thermal relay, and the control functions of a contactor, providing a simple, efficient, and safe protection and control solution for low-power motors in the 0.4A to 0.63A range. When selecting a motor, be sure to choose the appropriate model and current setting based on the motor's rated power and current.
