GV2-ME20C from Schneider Electric is a thermomagnetic قاطع الدائرة 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, حماية الزائد, phase-failure protection, and direct control functions.
أنا. Basic Parameters and Functions
1. التصنيف الحالي
Setting Current Range: 13-18أ, suitable for three-phase motors with a power of approximately 9kW.
Magnetic Tripping Current: 223أ (عن 12.4 أضعاف التيار المقنن), 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 ثواني.
3. Structure and Protection
3-Pole (3ص) Design: With a width of only 45mm, it saves installation space.
Protection Rating: IP20 (for the main unit) and IP55 (when equipped with a waterproof box), supporting dustproof and waterproof environments.
4. Certifications and Compliance
– Certified by CE and CCC, meeting international and Chinese electrical safety standards.
الثاني. Core Functions and Application Scenarios
1. Comprehensive Protection Capabilities
Short-Circuit Protection: Boasts an interrupting capacity of up to 15kA, which can quickly cut off short-circuit current to prevent equipment damage.
حماية الزائد: 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.
التحكم عن بعد: Can be equipped with an Under-Voltage Release (UVR) or Shunt Trip Release (SHR) to realize remote tripping.
Accessory Expansion: Supports auxiliary contacts (على سبيل المثال, GVAE11, GVAN11) and adapters (على سبيل المثال, GV2-AF3), which can be combined with contactors to form a complete starter system.
3. التطبيقات النموذجية
Industrial Field: Direct starting and protection of motors for pumps, المشجعين, الضواغط, إلخ.
Commercial Scenarios: Equipment with high reliability requirements, such as food processing machinery and packaging machinery.
ثالثا. Technical Details and Installation

3. Service Life and Maintenance
الحياة الميكانيكية: 100,000 العمليات; الحياة الكهربائية: 100,000 العمليات (تحت دورة العمل AC-3), significantly higher than that of ordinary circuit breakers.
Modular Design: Facilitates maintenance and replacement of components.
رابعا. Price and Procurement
1. سعر السوق
Retail Price per Unit: تقريبًا 126-180 يوان (data as of 2025). Discounts are available for bulk purchases.
2. Alternative Models
– For higher current requirements, GV2-ME21C (17-23أ) or GV3-ME20 (10-16أ) can be selected.
– For intelligent requirements, an upgrade to models with electronic trip units in Schneider’s TeSys series can be considered.
V. Selection and Precautions
1. المطابقة الحالية
– Select the setting range based on the rated current of the motor, وينصح بحجز أ 10%-20% margin to cope with load fluctuations.
2. منحنى التعثر
– The thermomagnetic tripping curve (magnetic tripping at 12.4×In) is suitable for the inrush current characteristics of motors, avoiding frequent false tripping.
3. Installation Environment
– تأكد من أن موقع التثبيت يتمتع بتهوية جيدة, and avoid high-temperature or humid environments that may affect the accuracy of thermal protection.
السادس. 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 (على سبيل المثال, 2003010304032561).
