1. Application areas
CJP-F series special surge protector for wind power system is widely used in wind power generation system. Reasonable installation can effectively protect wind power system such as wind turbine generator set, control system and box transformer. As a surge protector for the fan's 690V power supply system, it protects the safety and reliability of the fan's power supply system.
2. Features
Reliable thermal trip protection device.
400/690V IT or TN-C power system protection.
Large flow rate and low residual pressure.
Reliable fault display and remote signaling alarm.
The enclosure protection grade is IP 20, and the flame retardant grade is UL 94 V-0.
Comply with IEC 61643-11, GB/T 18802.11 standard.
