Power off and remove dust on the contact block
Measure contact resistance (shall be ≤ 50mΩ)
Check flexibility of mechanical linkage
- Annual Maintenance
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.
- Selection & Installation Guidelines

Compatibility: Confirm matching with GV2/GV3 series circuit breakers; not applicable for other series
Contact Configuration: Select 1NO+1NC (GVAE11), 2NO (GVAE20) or 2NC (GVAE02) according to control demands
Mounting Position: Choose GVAE11 for front mounting, GVAE14 for side mounting
Current Matching: Control circuit current shall not exceed 2.5A; select higher-specification products if overloaded
7.2 Installation Notes
Installation Sequence: Install circuit breaker first, then attach the contact block and fully lock the clip
Wiring Standard: 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
