Product Description
Safeguard your valuable electrical equipment and solar power installations with the genuine CHINT 2 Pole AC Surge Protective Device (NU6-II G/F 40/440). Engineered for low-voltage AC power distribution systems, this Class II surge arrester diverts dangerous high-voltage spikes and transient surges safely to ground before they can reach sensitive electronics, solar inverters, and household appliances.
Manufactured under strict international safety benchmarks (IEC/EN 61643-11) and certified with CE standards, it delivers a high nominal and maximum surge protection capacity of up to 40kA with a maximum continuous operating voltage (U_c) of 440V AC. Each module comes equipped with a clear visual operational indicator (Green for normal operation, Red for fault/replacement required) and pluggable cartridges for hassle-free maintenance without disconnecting main wiring. Ideal for residential distribution boards, commercial facilities, and grid-tied or hybrid solar PV power setups.
