Import Dm Series Current Transformer — Buy in Bulk from Supplier in China

The DM Series Current Transformer from Yueqing Heyi Electrical Co., Ltd. is designed to accurately scale primary currents down to standardized secondary outputs of 1A or 5A for metering and protection circuits. It operates within rated primary currents ranging from 5A to 5000A, with accuracy classes of 0.5 and 1.0 as per IEC 60044-1. The core is constructed from high-permeability silicon steel, and the winding insulation uses class B epoxy resin, ensuring thermal stability under continuous load.

Typical applications include energy metering in industrial switchgear, relay protection systems, and power quality monitoring. These transformers are commonly used in low to medium voltage distribution panels where precise current sensing is required. The standard insulation level is 12kV, and the transformer is rated for indoor use in dry, non-corrosive environments. Standard mounting is DIN rail or panel bolt-on, with optional flange mounts available for heavy-duty installations.

Buyers typically source this model for integration into control panels, energy management systems, and substation automation. The minimum order quantity is not specified in the listing and must be confirmed directly with the supplier. Packaging is in protective cardboard with foam inserts, and shipping terms such as FOB Ningbo or CIF are negotiable. Lead time for standard units is typically 15 to 25 days after order confirmation, subject to production scheduling.
