Product Description
Chint Over-voltage Under-voltage Protection Relay 230V/400V Home or Industrial Use in 1-phase or 3-phase
General
NU6-II series surge protector is suitable for AC 50Hz, rated voltage 230V/400V three-phase power distribution and control system, meets SPD level test, used to suppress transient overvoltage lower than equipment withstand shock overvoltage, discharge discharge Energy to protect system circuits and equipment.
It is suitable for grading with other series of surge protectors to realize a layered protection system, so that the low-voltage distribution system can be more widely and effectively protected.
Meet the standards: GB/T 18802.1, IEC 61643-1, EN 61643-11, and obtain CQC, CE, CB and other certifications.
1.1 IEC test category: Class II test (8/20us)
1.2 Number of poles: 1, 2,3, 4;
1.3 Electric ratings: 230/400V, AC50/60Hz;
1.4 Application: Protect electric system and on-loading electrical apparatus from thunder and instantaneous over-voltage;
1.5 Standard: IEC 61643-1, EN 61643-11
-
Complete flow capacity level to meet different location installation requirements
-
Uc (L-N) reaches 350V, Uc (L-PE) reaches 440V, and the work after accessing the system is safe and reliable.
-
The full range of 1P/2P/3P/4P pole products provides phase-to-phase and neutral-to-ground common-mode protection. The full range of 1P+N/3P+N poles provides phase-to-neutral and phase-to-phase Full-mode protection from neutral to ground, suitable for grounding systems such as TT and TN
-
GB 18802.1-2011 conformity assessment, CQC comprehensive certification
-
The cooperation relationship between SPD and backup protection circuit breaker has been fully verified by Shanghai Lightning Protection Center.
How to select surge protectors
a. The voltage should be ≤Uc; b. Up＜maximum impulse withstands; c. Different protectors should be selected according to various grounding system and protection mode.
