Celsa Plug-on current transformer

When establishing a new switchgear, one faces the decision of which current transformers to use. Essential quality features include the efficiency and versatility of the products. Efficiency is reflected in the space required, installation effort, and costs. If a highly efficient current transformer offers additional versatility in the form of variable application and mounting options, the purchasing decision is often already made.

The innovative plug-on current transformers of the Alo series combine all these aspects under a sealable and rotatable terminal cover. Most importantly, the integrated short-circuit bridge eliminates the need for a transformer disconnect terminal. This results in lower power losses and simultaneously benefits from more economical cable routing. Correspondingly, the transformers of the Alo series represent the most compact design currently available on the market and are optimally suited for a control cabinet due to their unbeatable space efficiency. The wide range of applications, such as in machinery and plant engineering, along with the versatile mounting options of the transformer, meet the demand for a sustainable future with secure energy supply. These features make the end product the most cost-effective and commonly available version of a plug-on current transformer. Despite reduced costs, the current transformers of the Alo series offer increased safety due to the integrated short-circuit bridge.
