Import Dm3n1 Series Three Phase Current Transformer — Buy in Bulk from Supplier in China

The DM3N1 Series Three Phase Current Transformer is a three‑phase device designed for precise current measurement in industrial power networks. It features an epoxy‑potted housing that protects the windings from moisture, dust and chemical exposure, allowing reliable operation in indoor or outdoor settings. A double‑screw fastening system secures the primary conductors and simplifies installation by eliminating the need for separate clamps. The transformer incorporates a wide inner window that can accommodate large‑diameter cables, expanding its suitability for diverse conduit sizes.

Current transformers of this class are typically built to IEC 61869‑2 specifications, with a standard accuracy class of 0.5 % and a typical burden rating of 5 VA at rated current. The epoxy insulation provides an insulation class of B, matching common industrial safety requirements, while the core is normally made from silicon steel laminations to minimise hysteresis loss. The portable form factor of the DM3N1 series reduces handling weight and enables rapid deployment during maintenance or retrofit projects. These typical characteristics align the device with power distribution, renewable energy farms and automated factory lines where continuous monitoring is essential.

The transformer is marketed for electrical distribution systems, solar‑panel inverters and industrial automation controllers, serving utilities, EPC contractors and plant engineers. Suppliers indicate flexible minimum order quantities and offer standard shipping documents such as CE and ISO certificates, with payment options including L/C and T/T. Prospective buyers should confirm the exact current rating, window dimensions and any required custom packaging with the supplier before placing an order.

Yueqing Heyi Electrical Co., Ltd. is located at #21 Shangyou Road Liushi Yueqing 325604, China. The company is classified as an imported tier supplier and holds a harbor trust tier on the platform, indicating a basic level of verification. Current response metrics show a response rate of 0 % and no recorded average response time, which suggests communication may require proactive follow‑up. The listing does not disclose production capacity, certifications beyond the generic ISO and CE statements, or specific lead‑time details.

The supplier offers the DM3N1 series as a ready‑to‑ship item and mentions flexible MOQ, but exact quantities must be discussed directly. Packaging is described as protective for transit, and the seller lists L/C and T/T as accepted payment methods. Buyers are encouraged to request a detailed datasheet and confirm any required customisations such as current rating or window size.
