 |
Motor protection circuit breaker, also known as motor protection type circuit breaker or motor protection circuit breaker, is an integrated control and protection device designed specifically for AC motors. It integrates the isolation and short-circuit breaking functions of circuit breakers, as well as the overload protection function of overload relays, and can replace the traditional combination scheme of "contactor+thermal relay+fuse", providing more reliable, accurate, and integrated protection and control for electric motors.
Model meaning
"GV2" refers to the type, "current" and "voltage" (3/4P) are modifiers, and "Motor protection Circuit Breaker" is the keyword.
The GV2 circuit breaker is a well-designed and reliable expert in motor protection. It integrates comprehensive protection functions and high breaking capacity in a compact size, making it a classic and widely used choice for industrial motor control circuits.
Main advantages:
Highly integrated: replacing the traditional solution of "circuit breaker+contactor+thermal relay", saving space and simplifying wiring.
Precise protection: Based on microprocessor technology, the protection curve is more matched with the motor's thermal characteristics, and the action is more accurate.
Rich functionality: Provides various electrical fault protection, status monitoring, and fault diagnosis.
Intelligence: Supporting remote control, status monitoring, and fault recording, it is the fundamental component of smart factories.
Reduce downtime: Quickly identify the cause of faults and shorten maintenance time.

Product quality
1.High protection accuracy and reliability
Accurate thermal memory: Its bimetallic overload protection can accurately simulate the heating curve of the motor, provide matching "inverse time limit" protection, avoid misoperation and refusal to move, and effectively extend the life of the motor.
Reliable breaking capacity: The short-circuit breaking capacity meets the standard requirements and can safely and reliably cut off the circuit when a fault occurs, protecting downstream equipment.
2. Mechanical durability and solid materials
Durable operating mechanism: The mechanical operating mechanism has a clear tactile feel and has undergone rigorous lifespan testing (usually tens of thousands of mechanical operations), ensuring stability even in frequent start stop situations.
Excellent shell material: The engineering plastic shell is flame retardant, impact resistant, and resistant to chemical corrosion. The internal metal components are sturdy and can adapt to harsh industrial environments.
3. The attachment system is complete and has strong compatibility
Modular design: Auxiliary contacts, shunt/undervoltage release and other accessories adopt standard modular design, easy installation, reliable connection, and excellent compatibility with the body.
Flexible expansion: The rich variety of accessories enables it to flexibly adapt to various control cabinet designs and automation system integration requirements.
4. Outstanding long-term stability and consistency
Stable performance: The product has high consistency, and after different batches and long-term use, its protective characteristics (such as trip curves) drift very little, ensuring long-lasting and stable protection effect.
Good temperature rise control: The internal conductive circuit design and material selection are reasonable, and the temperature rise is low during long-term operation at rated current, reducing thermal aging and ensuring service life.

International transport
When the quantity of goods is small and time is tight, and it needs to be transported to a designated location abroad, the three majorinternational express delivery companies are selected for transportation DHL,FEDEX,UPS
Sea freight/air freight
When there is a large quantity of goods and time is not urgent, we choose sea freight. We will choose a suitable freight company, who wil arrange for trucks to pick up the goods and transport them to the designated por for warehousing. Finaly, they will transpored by sea to the customer's desianated port, and the customer needs to pick up the goods with a bill of lading.
