China MR Series Current Transformer - Affordable Solutions from Reliable Suppliers and Factory
Flexible Mounting Options — Base-mounted for stable panel installation, or baseless for space-constrained and integrated cabinet layouts. Supports both terminal cover and open-terminal configurations.
High Cost-Effectiveness — Optimized manufacturing and material selection deliver a low-cost advantage while meeting standard performance requirements, ideal for budget-sensitive or bulk procurement projects.
Ultra-Wide Current Range — Rated primary current from 5A to 30,000A, covering small civil distribution systems to large industrial high-current environments.
Enhanced Safety — Terminal cover design protects internal connections against dust, moisture, and external mechanical forces, ensuring long-term operational safety.
The MR series current transformers utilize insulating tape winding as their core technology, making them a low-cost product that combines practicality and economy. The product series is comprehensively planned, including six sub-specifications to meet the basic needs of various current measurement scenarios, providing users with diverse choices.
Given their stable operating performance, affordable procurement cost, and design advantages adapted to the characteristics of the Southeast Asian power grid, this series of transformers is widely used in the power markets of Southeast Asian countries. Whether in industrial power distribution, commercial building power supply, or current monitoring of residential power facilities, they can be found everywhere, becoming a preferred component with outstanding cost-effectiveness in local basic power engineering projects.
