SCHNEIDER TeSys ® GV2/GV3 series motor circuit breakers

3.3 Electrical Release and Safety Functions

The series supports under voltage trip (UV) and shunt trip (SH) to enhance system safety. Under voltage trip can disconnect the circuit when the power supply is abnormal, preventing the motor from starting automatically when the voltage is restored; The shunt release supports remote disconnection. In addition, all operating handles can be locked in the "OFF" position with a padlock to achieve mechanical interlocking and comply with safety operation regulations.

3.4 Environmental adaptability and reliability

The working temperature range of the product covers -20 ℃ to+60 ℃ (enclosed installation up to+40 ℃), and the storage temperature is as low as -40 ℃. It has good anti vibration (5gn), anti impact (30gn) performance and flame retardant properties (960 ℃), suitable for complex environments in industrial sites. The protection level can be selected from IP20 to IP65 to meet the requirements of different installation scenarios.

Rich attachments and modular expansion

The TeSys series provides highly modular accessory systems that users can flexibly configure according to their needs

Signal contact module: including instantaneous auxiliary contacts (GV-AE/GV-AN), fault indication contacts (GV-AD), and short-circuit signal contacts (GV-AM), used for status feedback and system interlocking.

Electrical trip module: covering undervoltage and shunt trip coils with various voltages ranging from 24V to 600V.

Connection and busbar system: Provides 3-pole 63A busbar (GV2-G series), terminal block (GV2-G05), and flexible connection block for easy wiring inside the cabinet.

Operation and installation accessories: including external operating handle (padlockable), adapter board, compensation board, installation guide rail, etc., supporting cabinet door installation and remote operation.

Selection Guide and Installation Suggestions

5.1 Key steps for selection

Determine motor parameters: rated power, voltage, current, and starting characteristics.

Select circuit breaker type: Choose between thermal magnetic or electromagnetic based on protection requirements.

Check the breaking capacity: Ensure that Icu is greater than the expected short-circuit current at the installation point.

Select rated current: Select within the adjustable range of the circuit breaker based on the motor's full load current.

Confirm attachment requirements, such as signal contacts, trip coils, operating methods, etc.

Consider installation environment: temperature, humidity, protection level, vibration conditions.

5.2 Installation precautions

Ensure sufficient electrical clearance and creepage distance, and increase the spacing for high voltage (such as 690V) applications.

When multiple units are installed side by side, leave a gap of ≥ 9mm for heat dissipation or installation of side accessories.

It is recommended to use torque tools to tighten the wiring terminals to avoid being too loose or too tight.

For hazardous machinery, undervoltage trip wiring schemes that comply with INRS standards should be selected.

Application Value and Summary

Schneider Electric's TeSys series motor circuit breakers have become the preferred solution in the field of industrial motor protection due to their comprehensive product line, excellent protection performance, highly modular design, and extensive international certification. Whether it is the economic applicability of the domestically produced GV2 series or the high performance and reliability of the imported GV2/GV3 series, both can help users achieve:

Enhance system security: precise overload and short circuit protection to avoid equipment damage and accidents.

Enhance operational efficiency: Modular attachments and clear status indicators simplify maintenance and fault diagnosis.

Optimizing energy efficiency management: Combining EcoStruxure platform to achieve monitoring and optimization of energy use.

Ensure compliance: comply with multiple standards such as IEC, UL, CSA, CCC, etc., to facilitate smooth project acceptance.
