4.1 Internal Schneider Replacements

4.2 Markenübergreifender Wettbewerbervergleich

5. Anwendungsumgebungen & Typische Fälle

5.1 Empfohlene Anwendungen

Motor Control Circuit: Feedback circuit breaker ON/OFF status for PLC/DCS system monitoring

Alarm System: Trigger audible and visual alarms via NC contacts when the circuit breaker trips

Interlock Control: Prevent simultaneous startup of multiple motors and realize sequence control

Fernüberwachung: Transmit status signals to SCADA system for remote diagnosis

Safety Circuit: Form safety protection circuits together with emergency stop buttons

5.2 Nicht empfohlene Anwendungen

Main Circuit Usage: Rated current is only 2.5A, not applicable for motor main circuits

High-frequency Switching: Über 1000 switching cycles per hour will shorten service life

Severe Electromagnetic Interference Environment: Additional shielding is required to avoid malfunction

Humid/Corrosive Environment: IP20 protection is insufficient; install extra enclosure or select higher protection grade products

5.3 Typische Anwendungsfälle

Fall 1: Pump Unit Control in Wastewater Treatment Plant

Ausrüstung: 15kW submersible pump, GV2P32 circuit breaker + GVAE11 auxiliary contact

Konfiguration: NO contact of GVAE11 connected to PLC digital input module; NC contact connected to alarm circuit

Ergebnis: Real-time monitoring of pump operating status, automatic alarm and event recording upon faults

Fall 2: Conveyor System in Automotive Production Line

Ausrüstung: 12 conveyor lines, each equipped with GV2P32 + GVAE11

Konfiguration: GVAE11 contacts linked with PLC to realize sequential startup and interlock protection for conveyors

Merkmale: Mechanical linkage ensures accurate status feedback and reduces misjudgment of control systems

6. Fehlerbehebung & Maintenance Manual

6.1 Häufige Fehler & Lösungen

6.2 Maintenance Procedures

1. Tägliche Inspektion (Wöchentlich)

Check installation condition and ensure no looseness

Inspect terminals for overheating and looseness

Test contact switching to confirm synchronization with circuit breaker

2. Routinewartung (Jeder 6 Monate)

Power off and remove dust on the contact block

Kontaktwiderstand messen (shall be ≤ 50mΩ)

Check flexibility of mechanical linkage

3. Jährliche Wartung

Replace frequently used contact blocks

Test insulation performance of control circuits

Retighten all electrical connections

6.3 Quick Diagnosis Tips

No signal? Check installation and linkage first.

Contact welded? Limit current and cut switching times.

Signal interference? Separate wires, apply shielding and good grounding.

Loose fitting? Re-clip firmly and add shockproof measures for vibrating sites.

7. Auswahl & Installationsrichtlinien

7.1 Auswahlregeln

Kompatibilität: Confirm matching with GV2/GV3 series circuit breakers; not applicable for other series

Kontaktkonfiguration: Select 1NO+1NC (GVAE11), 2NEIN (GVAE20) or 2NC (GVAE02) according to control demands

Montageposition: Choose GVAE11 for front mounting, GVAE14 for side mounting

Aktuelle Übereinstimmung: Control circuit current shall not exceed 2.5A; select higher-specification products if overloaded

7.2 Installationshinweise

Installation Sequence: Install circuit breaker first, then attach the contact block and fully lock the clip

Verkabelungsstandard: Use 0.5–1.5mm² copper wires with tightening torque of 0.8–1.2Nm; avoid over-tightening

Clear Marking: Label NO/NC contacts to prevent wiring errors

Linkage Test: Manually operate the circuit breaker after installation to verify synchronous contact action

Protection Measures: Install extra enclosures for dusty or humid environments

8. Production Status & Ersatzlösungen

Current Status of GVAE11: In production, no discontinuation plan (as of June 2026)

Upgrade & Ersatzoptionen:

1. Funktionserweiterung: GV3 series models with built-in contacts (no extra assembly, fewer fault points)
2. Intelligent Upgrade: TeSys T series (with communication function for network-based status transmission)
3. Inländische Alternative: Compatible domestic GVAE11 models (lower cost with equivalent performance)
