Current transformers - ENTES
Current transformers from ENTES are precision measurement devices designed to step down high primary currents to a standardized, manageable secondary current (typically 5A or 1A) for metering, protection, and control applications.

Current transformers from ENTES are precision measurement devices designed to step down high primary currents to a standardized, manageable secondary current (typically 5A or 1A) for metering, protection, and control applications. These inductive components are engineered for accuracy classes from 0.2 to 5P, with rated primary currents ranging from a few amperes up to several thousand amperes. They feature robust insulation levels, with rated voltages up to 0.72 kV for low-voltage applications, and are available in various window sizes and mounting configurations, including bus-bar and cable types. The ENTES range includes both measuring and protection cores, often with multiple secondary windings for combined applications.
These current transformers are essential in electrical distribution systems, switchgear assemblies, and industrial control panels. They are widely deployed in power quality monitoring, energy management systems, and protective relaying schemes within sectors such as manufacturing, utilities, commercial buildings, and renewable energy installations. Their compact design allows integration into existing cubicles and motor control centers, providing accurate current sensing for metering and protection without direct connection to high-voltage circuits.
The ENTES current transformer category includes subcategories such as wound primary types, split-core transformers for retrofitting, and bushing-type units. Key article codes follow a structured format, for example, the series "ENTES CT-XX" where XX denotes the primary current rating and window diameter. Specific models like the ENTES CT-100/5A or CT-200/1A are common, with variants for different accuracy classes and secondary burdens. The range also encompasses summation transformers and special-purpose units for harmonic filtering applications.
