Description :
Qianwei CQW-251 is a high-performance T1 level power surge arrester designed specifically for low-voltage distribution systems. This product adopts a modular design and supports standard 35mm rail installation. It can be flexibly configured in the main distribution box or distribution cabinet, effectively responding to the instantaneous high-energy impact caused by direct lightning strikes or operating overvoltages. Its core adopts high-quality zinc oxide varistor and gas discharge tube combination technology, with a nominal discharge current capability of 25kA (10/350 μ s) and a voltage protection level Up<2.5kV, ensuring that sensitive equipment such as PLC controllers, frequency converters, UPS power supplies, etc. are protected from damage. The rated working voltage Ue of the product is 385VAC, suitable for 50/60Hz three-phase four wire system, complies with GB/T 18802.11 Type 1 standard and has passed CE certification. Its safety and reliability have been internationally recognized. Each module is equipped with a status indicator window: black indicates normal (OK), red indicates replacement (Replace), which facilitates quick inspection and maintenance by operation and maintenance personnel. The shell is made of flame-retardant PC material, which is resistant to high temperature and aging. The connection terminal supports the access of large cross-section cable, and the contact is stable and reliable. Widely used in industrial plants, data centers, communication base stations, medical equipment rooms, and intelligent buildings that require high power supply continuity, it is the first key line of defense for building a multi-level lightning protection system. It is recommended to cooperate with T2/T3 level SPDs to form graded protection and achieve full chain surge suppression.
