Why Choose the ABB CT4L310R/4 3-Phase Current Transformer?

The ABB CT4L310R/4 is a dedicated three-phase current transformer designed to extend the current measurement capability of ABB Universal Motor Controller systems. Supplied under ABB order code 1SAJ929500R0310, it forms part of the ABB 311531-FieldBusPlug product group and is intended for higher-current motor applications where direct current measurement by the motor controller is not sufficient.

The CT4L310R/4 has a 310 A rated primary current and a 4 A rated secondary current. The transformed secondary current is supplied to the compatible ABB UMC100.3 motor controller, enabling the controller to monitor and protect motors operating at substantially higher primary currents.

Designed as a three-phase current converter set, the CT4L310R/4 incorporates copper rails and provides an over-current limiting factor of FS 10. Its purpose-designed construction makes it suitable for industrial motor control centres, switchgear assemblies and automation systems requiring current monitoring for motors with operating currents extending up to 310 A.

Key Advantages

  • Extends compatible ABB Universal Motor Controller current measurement to applications up to 310 A.
  • Integrated three-phase current transformer set provides measurement across all three motor phases.
  • 310 A primary / 4 A secondary current transformation.
  • Designed to provide the secondary current required by the ABB UMC100.3.
  • Integrated copper rails simplify the primary current path through the transformer assembly.
  • Well suited to high-current industrial motor feeders, MCCs and switchgear assemblies.

Key Features

  • ABB CT4L310R/4 three-phase current transformer.
  • Designed for compatible ABB UMC100.3 Universal Motor Controller installations.
  • 310 A rated primary current.
  • 4 A rated secondary current.
  • Suitable for motor current measurement up to 310 A.
  • Three-phase current converter set.
  • Integrated copper rails.
  • FS 10 over-current limiting factor.
  • Fixed installation rather than snap-on mounting.
  • Purpose-designed accessory for high-current motor management systems.

Extending UMC100.3 Monitoring to Higher Motor Currents

Current transformers allow an electronic motor controller to monitor primary currents that exceed its direct measurement range. The ABB CT4L310R/4 converts the high motor feeder current into a proportional 4 A secondary current that can be measured by the compatible UMC100.3, allowing the controller's motor protection, monitoring and diagnostic functions to be applied to higher-current motors.

With a 310 A primary rating and integrated three-phase construction, the CT4L310R/4 provides a compact approach to monitoring all three motor phases. This makes it particularly useful in intelligent motor control centres where higher-power motors require the protection and diagnostic capabilities of an ABB Universal Motor Controller.

Typical Applications

  • ABB UMC100.3 Universal Motor Controller installations.
  • Higher-current three-phase motor feeders.
  • Intelligent motor control centres and MCC systems.
  • Industrial pumps, fans and compressor systems.
  • Conveyors and material handling equipment.
  • Industrial switchgear and motor protection systems.
  • Manufacturing and process automation installations.
