Ερωτήσεις:
What is the difference between a surge protector and a lightning arrester?
A lightning arrester handles higher voltage ranges (up to 1,000kV), while a surge protector is rated for lower voltages (less than 1.2kV). This product combines both Class B + C protection for comprehensive surge defense.
Can this surge protector be used in TT systems?
Yes, the AC T1 T2 1P+NPE 275V Surge Protector is universally suitable for TT systems, providing reliable protection for main distribution boards and installations.
What is the delivery time for mass production orders?
Mass production orders typically take 25 days for delivery, with options for air shipping, sea shipping, or express couriers like DHL/FEDEX/TNT/UPS.
