Extended Product Information
FAQs
What is the primary function of the TeSys GV3P80 circuit breaker?
The primary function is to provide thermal-magnetic protection for three-phase motors, safeguarding them against overloads and short circuits.
How do I adjust the thermal trip setting?
The thermal overload release current setting is adjustable via a control on the front of the breaker, typically ranging from 70A to 80A. Consult the product manual for specific adjustment instructions.
What is the breaking capacity of the GV3P80 at 400V?
The rated short-circuit breaking capacity (Icu) at 400V AC is 50kA.
Can this breaker be used for general electrical distribution circuits?
While it offers robust protection, it is specifically designed and optimized for motor circuit protection. For general distribution, other types of circuit breakers might be more appropriate, depending on the application's specific requirements.
What does 'phase failure sensitive' mean?
It means the breaker can detect a loss of one or more phases in a three-phase power supply, which can be critical for preventing motor damage.
What is the warranty period for this product?
Warranty information is typically provided by the seller or distributor. Please refer to your purchase documentation or contact the vendor for details on the warranty period and terms.
What are the dimensions of the GV3P80?
The breaker has a width of 136mm and a depth of 132mm. The exact overall dimensions may vary slightly depending on specific configurations, but it is designed for standard industrial panel mounting.
Troubleshooting
Breaker trips frequently under normal load.
Verify that the overload release current setting is correctly adjusted for the motor's full load amperage (FLA). Ensure the motor is not running under excessively heavy load conditions. Check for any mechanical issues with the driven equipment causing increased motor strain.
Breaker does not trip during a short circuit test.
Confirm that the magnetic trip setting is appropriately configured (typically 14xIn). Ensure the breaker is correctly wired and rated for the circuit's potential fault current. If the issue persists, the internal mechanism may be faulty, and the unit may need replacement.
Rotary handle is stiff or difficult to move.
Check for any obstructions around the handle or breaker. Ensure the breaker is correctly mounted and not under mechanical stress from adjacent equipment. Clean the handle mechanism and lubricate lightly if necessary, following manufacturer guidelines.
Breaker fails to reset after tripping.
Ensure the fault condition that caused the trip has been resolved. Check for any physical damage to the breaker's reset mechanism. If the fault persists, the breaker may be damaged and require replacement.
Pros and Cons
Pros
- Provides robust and reliable motor protection.
- Adjustable settings allow for precise customization.
- High breaking capacity ensures safety in fault conditions.
- Compliant with major international standards.
- Durable design for long operational life.
- Easy to install and operate.
Cons
- Requires correct adjustment of thermal and magnetic settings for optimal performance.
- Specific mounting requirements (DIN rail or panel with M4 screws) need to be considered.
- IP20 rating means it's suitable for indoor environments and requires additional protection in dusty or wet conditions.
- Primarily designed for motor circuit protection; may not be suitable for general power distribution applications without specific considerations.
Setup, Compatibility & Care
Setup:
The GV3P80 is designed for straightforward installation. It can be mounted directly onto a standard 35mm DIN rail by clipping it into place. Alternatively, it can be mounted onto a control panel using M4-sized screws for a more permanent fixture.
Wiring:
Connect the main circuit conductors to the EverLink BTR screw terminals. Ensure that all connections are secure and that the wiring gauge is appropriate for the rated current. For manual operation, the rotary handle can be rotated to the 'ON' or 'OFF' position.
Compatibility:
This breaker is compatible with three-phase motor applications up to 45kW at 400V. It is designed to comply with international standards such as IEC, UL, CSA, and ATEX, ensuring broad compatibility in various global installations. Its voltage rating ranges from 230V to 690V AC.
Care and Maintenance:
- Cleaning: Keep the breaker clean and free from dust and debris. Use a dry cloth for cleaning. Avoid using solvents or water.
- Inspection: Periodically inspect the terminals for tightness and check the rotary handle for smooth operation. Ensure the breaker is free from any visible damage.
- Environment: The breaker has an IP20 degree of protection, meaning it is suitable for indoor environments and protected against solid objects larger than 12mm. It should not be exposed to excessive moisture, corrosive atmospheres, or extreme temperatures outside its operating range of -20°C to +60°C.
