MES Series current transformer,Safe Plastic,DIN Rail and Panel Mounting

The MES series current transformers come in nine specifications. They feature a compact design, smaller than other current transformers with the same current ratio, and a flip-top terminal block design that effectively protects the secondary wiring terminals. They are equipped with relevant accessories and can be mounted on a DIN rail.

    Feature

    ■This current transformer is equipped with three integrated fixing methods to meet diverse installation requirements: Panel mounting, Din Rail mounting, and Busbar mounting. Each fixing mode is designed for stability and compatibility—panel mounting ensures secure attachment to electrical control panels, Din Rail mounting enables quick assembly on standard DIN rails for streamlined cabinet layout, and Busbar mounting allows direct fixation on power busbars, adapting to different spatial configurations and wiring scenarios of power systems.

    ■The product features a built-in hinged terminal cover, which not only provides effective protection for internal terminals against dust, moisture, and accidental contact but also facilitates convenient opening and closing during wiring, maintenance, or inspection. This thoughtful design enhances operational safety while simplifying on-site work procedures.

    ■With a compact structural design, the transformer occupies minimal installation space, making it ideal for use in dense electrical cabinets or systems with limited spatial resources. Its sleek and space-saving profile does not compromise performance, ensuring seamless integration with other electrical components without causing layout conflicts.

    ■In terms of current adaptation, the transformer supports a wide primary current range from 5A to 3000A. This broad capacity coverage allows it to cater to various low-voltage and medium-voltage power distribution scenarios, from small-scale industrial equipment to large-scale power supply systems, meeting the current measurement and protection needs of different power load levels.
