Bender CTAC60 Measuring Current Transformer

Description

Bender CTAC60 Measuring Current Transformer

Product Dimensions：

The Bender CTAC60 is a highly sensitive, circular measuring current transformer (CT) from the LINETRAXX® series. It is specifically designed to work with Bender’s residual current monitors (RCM/RCMS) and insulation fault location systems (EDS) to detect AC and pulsed DC fault currents.

Product Detailed Description

The CTAC60 serves as the “sensing eye” for monitoring systems. It converts small residual or fault currents flowing through the primary conductors into an evaluable measurement signal for a connected evaluator. Its large 60 mm internal diameter allows it to accommodate multiple large-gauge power cables or busbars, making it suitable for high-power distribution circuits.

Technical Parameters

Product Advantages

• High Sensitivity: Capable of detecting very low leakage currents (Type A), enabling early warning before a full system trip occurs.
• Broad Compatibility: Works seamlessly with Bender RCM420, RCMS460/490, and EDS440/460 series, making it a versatile component for both earthed (TN/TT) and unearthed (IT) systems.
• Robust Diagnostics: When paired with Bender monitors, it supports continuous monitoring of the connection between the CT and the evaluator.
• Flexible Installation: Can be mounted on a standard DIN rail or fixed directly to a panel using integrated mounting brackets.

Important Considerations (Precautions)

• Conductor Routing: All current-carrying conductors (L1, L2, L3, and N) must be routed through the CT. The Protective Earth (PE) conductor must never pass through the CT.
• Cable Centering: For maximum accuracy and to prevent nuisance tripping, cables should be centered within the CT opening.
• Shielding: Do not route shielded cables through the CT. If a shield must pass through, it must be pulled back and grounded outside the CT.
• Bending Radius: Observe the minimum bending radius of the primary conductors. They should not be bent sharply immediately before or after the CT.
• Wiring Distance: Use twisted-pair or shielded cabling for the connection to the monitor if the distance exceeds 1 meter to prevent electromagnetic interference.

Product Applications

• Data Centers & IT Infrastructure: Continuous monitoring of power supplies to prevent unplanned downtime due to insulation degradation.
• Industrial Manufacturing: Monitoring of large motor drives and production lines where high availability is critical.
• Hospitals: Used in medical IT systems (in conjunction with EDS) to locate insulation faults without interrupting power to life-support equipment.
• Renewable Energy: Monitoring for fault currents in wind turbines and large solar inverter stations.
