从China供应商批量进口3td Mechanical Interlocking Contactor

The 3TD mechanical interlocking contactor from Shanghai People Enterprise Group., Co is engineered to manage AC circuits at a rated voltage of up to 660 V and a current capacity of 300 A, with compatibility for both 50 Hz and 60 Hz systems. Its interlocking mechanism prevents simultaneous operation of linked contacts, which is critical for safety in systems where unintended energisation could cause damage or injury.

The contactor is designed for heavy-duty use in industrial environments, with high electrical and thermal resistance to ensure reliable performance under continuous load. Standard mechanical interlocking contactors in this class are typically constructed with silver alloy contacts for durability and low resistance, and they often include arc suppression features to extend contact life. The unit is suitable for motor control, lighting systems and other high-current applications where precise switching is required.

Industrial buyers such as manufacturing plants, HVAC system integrators and automation contractors use this contactor to enhance the safety and efficiency of their electrical installations. The supplier does not specify certifications in the listing, so buyers should confirm compliance with standards such as IEC 60947 or GB 14048, which are typical for such components. Request documentation to verify the interlocking mechanism’s reliability and the contactor’s performance under rated conditions.

Shanghai People Enterprise Group., Co operates from Malujiao Industrial Park in Beibaixiang, Yueqing, Zhejiang Province, with a postal code of 325603. The company is categorised as an imported-tier supplier, indicating it sources or manufactures components to international standards, though the listing does not provide further details on its production capabilities or quality control processes.

The supplier holds a harbor trust tier but shows a 0% response rate and no recorded average response time in the profile. No certifications, client references or production facility details are listed, so buyers should request third-party test reports, factory audits and examples of past projects to assess reliability and product quality.
