Import Ac Power Arrester Surge Protector — Buy in Bulk from Supplier in China

This AC power arrester surge protector is a Class C/D surge protective device (SPD) designed for installation on AC power distribution systems to limit transient overvoltages caused by lightning strikes and switching events. The unit features a compact form factor suitable for DIN-rail or panel mounting, with an LED status indicator for operational monitoring. Shenzhen Techwin Lightning Technologies Co., Ltd, based in Shenzhen's Nanshan district, positions this product for industrial and commercial electrical protection applications.

The surge protector employs metal oxide varistor (MOV) technology as its primary protection element, a standard approach in Class C/D devices for secondary and tertiary protection levels. Its construction includes a thermally protected disconnector to prevent catastrophic failure under sustained overvoltage conditions. The housing is designed for standard electrical enclosure compatibility, with terminal connections rated for typical AC power conductor sizes. Industry practice for this category of SPD includes surge current handling capacities measured in kiloamperes, with common ratings ranging from 10 kA to 40 kA per phase depending on application exposure level.

Typical buyers include electrical contractors, facility maintenance teams, telecommunications infrastructure operators, and OEMs integrating protection into control panels or distribution boards. The product serves applications where equipment downtime from voltage transients carries significant cost, including manufacturing plants, data centres, and building management systems. Importers should confirm with Shenzhen Techwin Lightning Technologies Co., Ltd the specific surge current rating, maximum continuous operating voltage (MCOV), and voltage protection level (Up) for their intended application, as these parameters determine compatibility with local electrical codes and the protected equipment's withstand capability.

Shenzhen Techwin Lightning Technologies Co., Ltd operates from Room 2909B, Epoch Elite Building on Nanshan Street in Shenzhen's Nanshan district, Guangdong Province, placing it within one of China's densest concentrations of electronics manufacturing and technology development. The company's 'harbor' trust tier and 'imported' supplier tier indicate it has been introduced to international trade platforms but shows limited response engagement, with a 0.00% response rate and no recorded average response time. This profile suggests buyers should anticipate potential communication delays and plan sourcing timelines accordingly.

The supplier's specialisation in lightning and surge protection technologies aligns with Shenzhen's established supply chain for electrical components, though the listing provides no verified factory audit information, production capacity figures, or named client references. The address format indicates a commercial office location rather than manufacturing premises, which is common for trading companies or smaller manufacturers in the region. Buyers should verify directly with Shenzhen Techwin whether the company holds ISO 9001 quality management certification or IEC 61643 product certifications, as these are standard requirements for SPD products in most markets but are not independently confirmed in available data.
