Schneider Electric GV2-PM08C is a 3-pole thermomagnetic motor protection サーキットブレーカー (rotary knob type) belonging to the TeSys GV2 series, with an adjustable current range of 2.5–4A. It is suitable for low-power three-phase motors and is commonly used for overload and short-circuit protection of equipment such as fans, pumps, and small compressors. Supporting DIN rail mounting, it is ideal for scenarios like school cafeteria kitchens and building electromechanical systems. Below are the complete specifications and core details:

Data is based on IEC standards; actual matching shall be determined by the motor’s rated current
Core Functions & Advantages
- Dual Protection: Thermal overload protection (adjustable from 2.5–4A) + electromagnetic instantaneous short-circuit trip (approx. 51あ), effectively isolating faults.
- Integrated Design: Replaces the combination of “サーキットブレーカー + overload relay”, simplifying the circuit, reducing costs and potential fault points.
- Easy Installation: DIN rail mounting with clear wiring; the knob features on/off indicators for quick maintenance.
- Environmental Adaptability: Operating temperature range from -25℃ to +60℃; equipped with environment-compensated thermal trip, suitable for multiple scenarios such as kitchens and equipment rooms.
典型的なアプリケーションシナリオ
School Cafeteria Kitchens: Exhaust fans, small water pumps, food processing equipment.
Building Automation: Fresh air units, small cooling towers, rolling shutter door motors.
Laboratories/Small Production Lines: Low-power mixers, conveyors, vacuum pumps.
Selection & Replacement Recommendations
- Matching Motor Rated Current: Set the current to 1.05–1.1 times the motor nameplate current. 例えば, a 3A motor can be set between 3–3.5A.
- Replacement Compatibility: Directly replaceable with the same series GV2-PM08C or GV2P08 (imported model). It shares the same mounting dimensions as GV2-ME08C (push-button type), differing only in operation method.
- Accessory Expansion: Compatible with auxiliary contacts (例えば, GV2-AS11) and alarm contacts to meet remote signal feedback requirements.
Procurement & Packaging
Packaging: 1 unit/box, 20 units/case.
Price Reference: Domestic in-stock price is approximately RMB 110–135 per unit (as of December 2025); the imported version (GV2P08) is priced higher.
