Certification and Standards
The scope of application of the certification type standard number
Safety certification IEC/EN 60947-4-1 for low-voltage switchgear
Electromagnetic compatibility EN 61000-6-2/6-4 industrial environment anti-interference
Low-energy consumption coil design in accordance with energy efficiency standard IEC 60470 (CoC V class)
Marine certified DNV-GL/ABS Marine power System (Salt spray resistant version is required as an option)
Precautions
1. Coil voltage matching
• C-Z.V1 is a dedicated model for 24V DC. Incorrect connection to AC power supply will cause the coil to burn out
2. Arc extinguishing protection
For frequent on-off scenarios (> 600 times per hour), arc extinguishing grilles (optional UNO-ARC) need to be installed.
3. Maintenance cycle
It is recommended to check the contact thickness (wear amount < 0.5mm) every 50,000 operations.
4. Fault Diagnosis
• Abnormal noise: Check for fluctuations in power supply voltage (±10% allowed) or mechanical jamming
