Product Information

Full details

The Schneider Electric GV2P08 is a three-pole motor circuit breaker designed for 3-phase motor applications up to 1.1-1.5kW at 400V. It offers reliable thermal-magnetic protection and a high breaking capacity of 100kA at 400V, ensuring safety and operational continuity. A key benefit is its adjustable thermal range for precise motor protection. However, its primary function is motor protection, not general circuit overload protection.

Extended Product Information

FAQs

What is the primary function of the Schneider Electric GV2P08?

The GV2P08 is a motor protection circuit breaker designed to protect three-phase motors from overloads and short circuits, ensuring motor longevity and operational safety.

What is the adjustable thermal range?

The thermal trip current can be adjusted between 2.5 Amps and 4 Amps, allowing precise protection tailored to the specific motor's current draw.

What is the maximum voltage and current rating?

The breaker is rated for up to 690V AC and a nominal operational current of 4A. The adjustable thermal range is 2.5-4A.

Can this breaker be used for single-phase motors?

No, the GV2P08 is specifically designed for three-pole (three-phase) motor applications.

How do I reset the breaker after it trips?

Once the fault condition is cleared, the breaker can typically be reset by pushing the ON/OFF rotary handle to the OFF position and then to the ON position. If it trips again, investigate the cause of the trip.

What is the breaking capacity?

The GV2P08 has a breaking capacity of 100 kA at 400V, meaning it can safely interrupt fault currents up to that level.

What type of terminals does it use?

It features screw clamp terminals for secure electrical connections.

Troubleshooting

Breaker trips immediately upon motor startup

The thermal setting may be too low for the motor's startup current. Increase the thermal adjustment setting within the 2.5-4A range, ensuring it remains below the motor's maximum allowable current.

Breaker trips intermittently during normal operation

Check for motor overload (e.g., mechanical binding, excessive load). Verify the thermal setting is correctly matched to the motor's FLA. Inspect wiring connections for looseness or damage.

Breaker does not reset after tripping

Ensure the fault condition that caused the trip has been cleared. If the breaker has been subjected to a severe short circuit, it may need replacement. Contact a qualified electrician if the issue persists.

Breaker is warm to the touch during operation

Some warmth is normal due to current flow. However, excessive heat indicates a potential issue. Check terminal connections for tightness and ensure the thermal setting is appropriate for the load.

Pros and Cons

Pros

  • Provides robust thermal-magnetic protection for motors.
  • Adjustable current setting allows for precise motor matching.
  • High breaking capacity ensures safety in fault conditions.
  • Durable construction with a long operational life for the handle.
  • Compact size saves space in electrical enclosures.

Cons

  • Primarily designed for motor circuit protection, not general-purpose circuits.
  • Requires careful setting of the thermal range to prevent nuisance tripping or inadequate protection.
  • Screw terminals may require more torque and specific preparation than spring-loaded types.
  • Not suitable for DC circuits.

Setup, Compatibility & Care

Setup:

  1. Mounting: The GV2P08 is designed for panel mounting, typically on a DIN rail or via screw mounting within an enclosure.
  2. Wiring: Connect the three power input phases to the upstream terminals and the three output terminals to the motor. Ensure screw terminals are tightened to the recommended torque to guarantee a secure connection.
  3. Setting Adjustment: Adjust the thermal trip current using the rotary dial to match the motor's rated full-load current (FLA). The range is from 2.5A to 4A. Consult the motor's nameplate and relevant electrical codes for proper setting.

Compatibility:

  • Voltage: Suitable for circuits up to 690V AC.
  • Current: Designed for motors with a rated operational current of 4A and an adjustable thermal range of 2.5-4A.
  • Phase: Specifically for 3-phase AC motor applications.

Care:

  • Cleaning: Periodically clean the exterior of the breaker with a dry or slightly damp cloth. Ensure the unit is de-energized before cleaning.
  • Inspection: Visually inspect terminals for signs of corrosion or overheating. Check that the rotary handle moves freely.
  • Testing: Although not typically user-serviceable, professional periodic testing may be required depending on site regulations.
