Automatic Transfer Switch (ATS) VCX 125A 4P, suitable for emergency power supply systems with a frequency of 50 or 60 Hz and a rated voltage of 400 V AC. The switch is mainly used to test the functionality of the main power source or the emergency power source. When the normal power source fails, the emergency power source is immediately connected, ensuring continuity of supply, reliability, and safety.

The NLQ4 features:

• Durable construction
• Reliable switching
• Easy installation and maintenance
• Long service life

The maximum current for single-phase and three-phase systems is 125 A.
