Second-hand Inspection Checklist (for used-market purchase)

1. Check housing for cracks, burn marks or burnt terminal lugs
2. Rotary knob should turn smoothly without jamming
3. Verify normal closing and opening operations
4. Cross-check nameplate: GV2-P22, 20-25 A; do not confuse with GV2-P21 (17-23 A)
5. Distinguish models: GV2-P uses rotary knob; GV2-ME uses lever handle. Different housings, not directly interchangeable.

9. Rotary knob turns smoothly, ON/OFF positions clear, no sticking.
10. Housing free of cracks; terminal lugs without burning or erosion.
11. Perform manual close-open test. If possible, verify thermal-trip and magnetic-trip functions.
12. Distinguish GV2-P (imported, depth 97 mm) vs GV2PM (domestic, depth 91 mm). Housings are not directly interchangeable.

Application Scenarios for Schneider GV2-P22 Motor Circuit-Breaker

GV2-P22 (adjustable 20-25 A, max 11 kW three-phase motor @400 V) belongs to TeSys GV2-P rotary-knob thermal-magnetic manual motor starter. It integrates short-circuit protection, motor overload protection, phase-failure protection and main-circuit isolation. It performs local motor on-off control and is frequently paired with contactors and overload relays for motor starting circuits. Widely deployed for small-to-medium three-phase motors in industrial machinery, conveyor lines, HVAC, light lifting and pump systems.

✅ Typical Load Matching (400 V three-phase reference)

Matched motor rating: 7.5 kW ~11 kW three-phase asynchronous motor

Note: Only select this model when the motor full-load current falls within the 20-25 A window. Do not over-size the setting for smaller motors, otherwise overload protection will be lost.

1. Industrial Equipment Applications
2. Machine-tool equipment

Drilling machines, small milling machines, grinders, light cutting equipment; machine-tool cooling pumps, hydraulic-station oil-pump motors.

Function: Instant tripping for motor stall, overload and winding short-circuit. Rotary knob provides local manual switching plus isolation for maintenance.

2. Conveyor & material-handling lines

Belt conveyors, roller conveyors, small elevators, sorting-equipment drive motors.

Advantage: Compact DIN-rail installation for dense cabinet layout. GV2-AE fault-alarm block can be added to send fault signals to PLC.

3. Fan & HVAC systems

Industrial centrifugal fans, cabinet fans, workshop exhaust fans, air-handling-unit fan motors.

Suited for fan-type high-inrush-current loads; thermal-magnetic characteristic tolerates starting surge while protecting against sustained overload.

4. Pump applications

Circulation pumps, sewage pumps, booster pumps, small hydraulic oil pumps.

Sewage pumps are prone to rotor stalling; built-in phase-failure protection prevents motor burnout from single-phasing. Rotary knob provides local switching and maintenance isolation inside control cabinets.

2. Control-cabinet Integration
3. Direct-on-line motor starter circuits (most common)

Scheme 1: Stand-alone GV2-P22 for local manual protection & switching for small motors without remote control.

Scheme 2: GV2-P22 + LC1D contactor forming a complete DOL starter: circuit-breaker provides short-circuit & overload protection; contactor executes PLC-based remote start-stop.

Classic configuration widely used inside PLC cabinets and MCC motor-control boxes.

2. Local field control boxes

Compact on-machine local control enclosures. Rotary knob switches motor and provides electrical isolation in OFF position, removing need for separate disconnector.

3. Other Industry Uses
4. Logistics & light lifting equipment

Small winches, auxiliary lifting motors (not for primary hoist safety circuits).

2. Plastics-processing machinery

Auxiliary small extruder drives, hopper feeding motors, mixer motors.

3. Marine / offshore auxiliary equipment

GV2-P series carries full marine classification-society approvals for on-board auxiliary pumps and ventilation fans inside engine compartments. ⚠️ Domestic GV2PM lacks full marine certifications; imported GV2-P must be specified for marine projects.

❌ Not-Recommended Applications

1. Not intended for single-phase loads or lighting circuits: Optimized specifically for motor protection logic, not general-purpose distribution.
2. Motor power >11 kW @400 V: Exceeds setting-current range; upgrade to GV3-series.
3. Downstream of VFD output terminals: Cannot connect to inverter output side. Only install on VFD input supply side for upstream protection.
4. Frequent forward-reverse jog-cycle operation: Add contactor for repeated switching; avoid frequent manipulation of the GV2-P rotary knob to preserve mechanical service-life.

💡 Selection & Operation Tips

1. Adjust rotary setting dial strictly according to motor nameplate full-load current. Do not simply turn to maximum 25 A; set to 21 A for a motor rated 21 A.
2. Remote fault-signal output requires add-on GV2-AE fault-contact block; no alarm output built-into unit.
3. GV2-P22 is imported rotary-knob variant. While protection parameters match lever-handle GV2-ME22, physical depth differs; check cabinet depth for retrofit replacement.
4. For used-unit deployment: Prioritize functional trip-test rather than cosmetic inspection only.
