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, linee di trasporto, HVAC, light lifting and pump systems.

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

Potenza motore corrispondente: 7.5 kW ~11 kW three-phase asynchronous motor

Nota: 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

Macchine perforatrici, small milling machines, smerigliatrici, light cutting equipment; machine-tool cooling pumps, hydraulic-station oil-pump motors.

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

2. Trasportatore & material-handling lines

Trasportatori a nastro, trasportatori a rulli, piccoli ascensori, sorting-equipment drive motors.

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

3. Fan & Sistemi HVAC

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

Pompe di circolazione, pompe per fognature, 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 (più comune)

Schema1: Stand-alone GV2-P22 for local manual protection & switching for small motors without remote control.

Schema2: GV2-P22 + LC1D contactor forming a complete DOL starter: circuit-breaker provides short-circuit & protezione da sovraccarico; 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. Logistica & light lifting equipment

Piccoli argani, auxiliary lifting motors (not for primary hoist safety circuits).

2. Plastics-processing machinery

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

3. Marino / 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. Potenza del motore >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.
