GV2-ME20C from Schneider Electric is a thermomagnetic disjoncteur specifically designed for motor protection. It is suitable for AC circuits with a frequency of 50/60Hz and a voltage up to 690V, providing short-circuit protection, protection contre les surcharges, phase-failure protection, and direct control functions.
je. Basic Parameters and Functions
1. Courant nominal
Setting Current Range: 13-18UN, suitable for three-phase motors with a power of approximately 9kW.
Magnetic Tripping Current: 223UN (about 12.4 fois le courant nominal), enabling rapid response to short-circuit faults.
2. Tripping Characteristics
Thermomagnetic Trip Unit: Combines long-time delay protection against overload (via thermal element) and instantaneous protection against short-circuit (via electromagnetic element).
Tripping Class: Complies with IEC Standard Class 10A, ensuring the overload current is cut off within 10 secondes.
3. Structure and Protection
3-Pole (3P.) Design: With a width of only 45mm, it saves installation space.
Indice de protection: IP20 (for the main unit) and IP55 (when equipped with a waterproof box), supporting dustproof and waterproof environments.
4. Certifications et conformité
– Certified by CE and CCC, meeting international and Chinese electrical safety standards.
Ii. Core Functions and Application Scenarios
1. Comprehensive Protection Capabilities
Protection contre les courts-circuits: Boasts an interrupting capacity of up to 15kA, which can quickly cut off short-circuit current to prevent equipment damage.
Protection contre les surcharges: Built-in thermal relay triggers tripping through the deformation of bimetallic strips, responding to motor overheating.
Phase-Failure Protection: Automatically detects three-phase current imbalance to prevent motor burnout due to phase failure.
2. Control and Expansion
Manual Operation: Button-type control, supporting local start/stop and locking functions.
Télécommande: Can be equipped with an Under-Voltage Release (UVR) or Shunt Trip Release (SHR) to realize remote tripping.
Accessory Expansion: Supports auxiliary contacts (par ex., GVAE11, GVAN11) and adapters (par ex., GV2-AF3), which can be combined with contactors to form a complete starter system.
3. Applications typiques
Industrial Field: Direct starting and protection of motors for pumps, les fans, compresseurs, etc..
Commercial Scenarios: Equipment with high reliability requirements, such as food processing machinery and packaging machinery.
III. Technical Details and Installation
1. Adaptabilité environnementale
Température de fonctionnement: -20℃ à +60℃, with a built-in temperature compensation function to ensure stability in different environments.
Storage Temperature: -40℃ to +80℃, adapting to extreme transportation and storage conditions.
2. Méthode d'installation
Montage sur rail DIN: Compatible with TH35-7.5mm rails, supporting vertical or horizontal fixing.
Méthode de câblage: Screw-in terminals, suitable for wires with a cross-sectional area of 2.5mm² or less, with a tightening torque of 1.7N·m.
3. Service Life and Maintenance
Durée de vie mécanique: 100,000 opérations; Durée de vie électrique: 100,000 opérations (under AC-3 duty cycle), significantly higher than that of ordinary circuit breakers.
Conception modulaire: Facilitates maintenance and replacement of components.
IV. Price and Procurement
1. Market Price
Retail Price per Unit: Environ 126-180 RMB (data as of 2025). Discounts are available for bulk purchases.
2. Modèles alternatifs
– For higher current requirements, GV2-ME21C (17-23UN) or GV3-ME20 (10-16UN) peut être sélectionné.
– For intelligent requirements, an upgrade to models with electronic trip units in Schneider’s TeSys series can be considered.
V. Sélection et précautions
1. Correspondance actuelle
– Select the setting range based on the rated current of the motor, et il est recommandé de réserver un 10%-20% margin to cope with load fluctuations.
2. Courbe de déclenchement
– The thermomagnetic tripping curve (magnetic tripping at 12.4×In) is suitable for the inrush current characteristics of motors, avoiding frequent false tripping.
3. Environnement d'installation
– Ensure the installation location has good ventilation, and avoid high-temperature or humid environments that may affect the accuracy of thermal protection.
Vi. Certification and Compliance Inquiry
– The compliance of the product can be verified by accessing the “Product Certificate Inquiry” function on Schneider Electric’s official website and entering the model or CCC certificate number (par ex., 2003010304032561).
For further technical support or customized solutions, it is recommended to contact the local service center of Schneider Electric or visit its official website for detailed information.
