Import 6ka L7 1p2p3p4p Mcb Circuit Breaker 32a 63a — Buy in wholesale FOB from Supplier in China

The 6KA L7 miniature circuit breaker from Guangzhou Golden Electric Co., Ltd. provides overcurrent protection in 1P, 2P, 3P and 4P pole configurations with rated currents of 32A and 63A. Its 6kA breaking capacity at 230/400V AC allows it to interrupt fault currents without sustaining damage, a critical parameter for distribution panel safety. The breaker mounts on standard 35mm DIN rail and complies with IEC 60898-1, the governing standard for domestic and similar installations. The housing is thermoplastic with copper alloy internal contacts, a combination chosen for thermal resilience and conductivity.

The L7 series uses a current-limiting design that restricts let-through energy during a short circuit, reducing thermal stress on downstream cables and equipment. The 1P variant protects single-phase circuits, while 2P, 3P and 4P versions address split-phase and three-phase systems with neutral protection where required. The 32A rating suits lighting and small appliance sub-circuits; 63A covers higher-load applications such as motor feeders or main incoming protection. Trip characteristics are typically B, C or D curve, though the buyer should confirm which curve this stock carries, as it determines the magnetic trip threshold and compatibility with inductive loads.

Importers in the electrical trade source this MCB for building infrastructure, manufacturing plant distribution, and energy sector panel builds across residential, commercial and industrial segments. The compact 17.5mm width per pole (standard for this class) maximises panel space efficiency. Guangzhou Golden Electric operates from Huangpu District, Guangzhou, with shipping typically ex-FOB Guangzhou port. Buyers should confirm the exact curve type, terminal capacity for conductor sizes, and whether supplementary accessories such as auxiliary contacts or shunt trips are available for this series.

Guangzhou Golden Electric Co., Ltd. is located at Building C, 39 Bigang Road, Huangpu District, Guangzhou, Guangdong Province, with postal code 510000. The company holds a harbor trust tier on the platform, which represents a baseline verification level rather than an audited or gold-tier status. Its response rate is recorded at 0.00 percent with an average response time of zero hours, indicating no recent quotation activity or that response metrics have not yet populated. Buyers should treat this as an unvalidated engagement profile and confirm responsiveness directly before placing orders.

The listing promotes the 6KA L7 MCB series as the core product, with no additional catalog breadth disclosed in the source data. The supplier does not state its year of establishment, factory size, annual output, or client references, so claims about scale or experience cannot be verified from this profile alone. The address places it within Guangzhou's industrial corridor, a region with dense electrical component manufacturing, though this geographic concentration does not alone confirm production capability. Buyers are advised to request factory audit reports, ISO 9001 certification, and IEC test reports specific to the L7 series before committing to volume orders.
