Product Description

The Allen-Bradley 1411-2SHT-201 is a solid-core current transformer with a 200 Amp primary to 5 Amp secondary ratio (200:5A). It features a rectangular outer shape and a 1.13-inch (approx. 28.7 mm) inner diameter window, through which the primary conductor passes. As a solid-core CT, it requires the primary circuit to be disconnected and passed through the transformer’s window during installation. This type of CT is commonly used for accurate current measurement in industrial and commercial electrical systems.

Product Advantages

• Accurate Current Measurement: Provides a precise and scaled-down representation of the primary current, essential for accurate metering and protection applications.
• Robust Construction: Solid-core design offers durability and stability in industrial environments.
• Standardized Output: The 5A secondary output is a common standard, allowing for easy compatibility with a wide range of metering devices, relays, and power monitors.
• Reliability: As an Allen-Bradley product, it is manufactured to high-quality standards, ensuring long-term reliability and performance.
• Versatility: Suitable for various power monitoring and protection applications in low-voltage systems.

Precautions

• Installation: As a solid-core CT, the primary conductor must be physically threaded through the transformer’s window. This requires the primary circuit to be de-energized and disconnected during installation.
• Secondary Circuit: Never operate a current transformer with an open-circuited secondary when the primary is energized. Doing so can induce extremely high voltages in the secondary winding, leading to dangerous shock hazards, insulation breakdown, and permanent damage to the CT. Always ensure the secondary terminals are short-circuited or connected to a proper load (meter, relay) before energizing the primary.
• Polarity: Observe correct polarity when connecting the CT. Incorrect polarity can lead to erroneous readings or improper operation of protective devices. The CT typically has markings (e.g., H1-H2 for primary, X1-X2 for secondary) to indicate polarity.
• Overload Protection: While CTs are robust, ensure the primary current does not consistently exceed the rated primary current to prevent saturation or damage over time.
• Insulation: Ensure proper insulation of primary conductors passing through the CT to maintain electrical safety.
• Trained Personnel: Installation and maintenance should only be performed by qualified electrical personnel following all local electrical codes and safety regulations.

Product Applications

The Allen-Bradley 1411-2SHT-201 current transformer is widely used in various electrical distribution and control applications for current sensing and measurement:

• Power Monitoring Systems: Providing current data to Allen-Bradley PowerMonitor products and other energy management systems for load profiling, cost allocation, and energy efficiency initiatives.
• Protective Relaying: Supplying current inputs to protective relays for overcurrent, ground fault, and other protection schemes in switchgear and motor control centers.
• Ammeter Measurements: Used with panel-mounted ammeters to display current levels in electrical circuits.
• Motor Control Centers (MCCs): Monitoring current draw for individual motors for overload protection and performance analysis.
• Load Balancing: Providing data for balancing loads across phases in three-phase systems.
• Generator and Transformer Monitoring: Sensing current in generator outputs or transformer feeders for operational monitoring.
