Protection Unit cabinet accessories  

 

Description:

• Adopt PTC and diode, integrated design of the security unit for over-voltage and over-current, with the FS and the over-voltage alarm function
• Fast PTC, fast response
• Special structure can prevent reverse insertion.
• Fulfil gas discharge tube and solid installation
• Copper connection wiring methods effectively improve the reliability of protective
• FS reaction speed: 6 seconds

 Protective performance:

 

1.Overvoltage

• DC breakdown voltage Udc ≤ 260V
• Pulse breakdown voltage Umax ≤ 800V

2.Over-current

• Room temperature resistance: ≤ 22Ω, a, b-line difference between the resistance ≤ 2Ω
• Non-operating current: 90mA, 1h non-action
• Fail-safe performance: When the discharge current up to 2.5A (RMS), the
• Discharge circuit of a line and b line in the ground within 5-15 S
•
