Detailed Specifications and Core Information of Schneider GV2ME08C
Schneider GV2ME08C is a TeSys GV2 series thermal-magnetic motor circuit breaker (commonly known as a “motor protection switch”). Its core function is to provide overload protection and short-circuit protection for small three-phase/single-phase motors, while also featuring manual on/off control. It is widely used in motor control circuits such as machine tools, المشجعين, and pumps.
| Item | Specific Parameters |
| تفسير النموذج | GV2 = Series Name (Thermal-Magnetic Motor Circuit Breaker); ME = Knob Operation + Manual Reset; 08 = Frame Size; C = Trip Curve (النوع ج, suitable for motor-type inductive loads) |
| تصنيف التشغيل الحالي (Ie) | Adjustment range: 4 ~ 6 أ (stepless adjustment via knob to match the motor’s rated current) |
| تصنيف جهد التشغيل (Ue) | AC-3 Category: 415 V (commonly used in three-phase motor circuits); AC-1 Category: 440 V (for resistive loads) |
| تصنيف الجهد العزل (Ui) | 690 V |
| Rated Short-Circuit Breaking Capacity (وحدة العناية المركزة) | 15 kA at 415 V (meets short-circuit protection requirements for conventional industrial scenarios) |
| وظائف الحماية | Thermal-magnetic trip: Overload → Thermal trip (delayed action); Short circuit → Magnetic trip (instantaneous action) |
| طريقة التشغيل | Front-panel knob operation (on/off + current adjustment), manual reset |
| طريقة التثبيت | Standard DIN rail mounting (35 mm rail, industrially universal) |
| جهات الاتصال المساعدة (Optional) | Requires matching auxiliary contact modules (على سبيل المثال, GV2-AUX01 Normally Open, GV2-AUX02 Normally Closed); no built-in auxiliary contacts |
| توافق الملحقات | Supports installation of undervoltage releases, remote control modules, إلخ. (must be purchased separately) |
| مواد الإسكان | Engineering plastic (flame-retardant, impact-resistant) |
| فئة الحماية | IP54 (dustproof, splash-proof, suitable for cabinet installation or slightly humid environments) |
| Applicable Motor Power (Reference) | 380 V three-phase motor: تقريبًا 2.2 ~ 3 KW (specifically match the actual motor current) |
الثاني. Core Features and Application Scenarios
1. Core Advantages
– Precise Protection: Adopts thermal-magnetic trip principle; overload protection can be compensated with ambient temperature, and short-circuit protection acts instantaneously to avoid motor burnout.
– Easy Operation: Directly adjust the rated current via the knob without additional tools; on/off status is intuitively visible.
– Strong Compatibility: Supports rail mounting and can be combined with Schneider TeSys series contactors and relays to form a complete motor control circuit.
– Durable and Reliable: Industrial-grade design with vibration resistance, electromagnetic interference resistance, and long service life.
2. سيناريوهات التطبيق
– Protection and control of the main circuit for small three-phase asynchronous motors (على سبيل المثال, fan motors, water pump motors, conveyor belt motors).
– Overload/short-circuit protection for motors in machine tools, automation equipment, and electrical control cabinets.
– Protection for single-phase motors (confirm that the motor current is within the 4~6 A range) (على سبيل المثال, small compressors).
ثالثا. Selection and Usage Notes
1. المطابقة الحالية: Must adjust the circuit breaker knob to the corresponding value (within the 4~6 A range) according to the “rated operating current” on the motor nameplate; do not use beyond the specified range.
2. نوع التحميل: Type C trip curve is specifically designed for motor-type inductive loads; it is not recommended for pure resistive loads (على سبيل المثال, heating tubes).
3. جهات الاتصال المساعدة: If remote control or fault indication is required, separately select auxiliary contact modules (على سبيل المثال, GV2-AUX01 1NO, GV2-AUX02 1NC).
4. Installation Environment: With a protection class of IP54, avoid direct exposure to rain and environments with excessive dust concentration; it is recommended to install it in an electrical control cabinet.
5. Replacement and Upgrade: For a larger current range, select models in the same series such as GV2ME10C (6~10 A) or GV2ME14C (10~14 A); for intelligent protection, upgrade to the TeSys GV3 series (with digital display and communication functions).
رابعا. الأسئلة المتداولة
– س: Can the GV2ME08C directly replace a fuse?
أ: Yes! It provides dual protection against overload and short circuits, offering superior functionality compared to a single fuse. It is reusable without the need to replace the fuse element, making it more suitable for long-term motor protection.
– س: Does it support remote tripping?
أ: لا, it does not support remote tripping natively. To achieve remote control, you need to install a remote control module (على سبيل المثال, GV2-ME series remote operation accessories) or cooperate with a contactor.
– س: Can it be used for single-phase motors?
أ: Yes, it can be used for single-phase motor protection as long as the motor’s rated current is within the 4~6 A range and the voltage meets the requirements (AC 220V falls within the Ui 690V range).
