1)protection Unit cable accessories 2)Fast PTC,fast respones 3)Fulfil gas discharge tube and soild installation

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 functionFast PTC, fast responseSpecial structure can prevent reverse insertion.Fulfil gas discharge tube and solid installationCopper connection wiring methods effectively improve the reliability of protectiveFS reaction speed: 6 seconds

 Protective performance:

1.Overvoltage

DC breakdown voltage Udc ≤ 260VPulse breakdown voltage Umax ≤ 800V

2.Over-current

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