3KC ATC5300 Automatic Transfer Control Device
Automatic transfer with the transfer control device 3KC ATC5300

The transfer control device 3KC ATC5300 is equipped with two motor-driven circuit breakers and serves as a transfer system that automatically or manually switches between two power supply systems in low-voltage power distribution applications.

In particular, the transfer control device 3KC ATC5300 is deployed where a power failure is especially critical, e. g. in hospitals, in conjunction with UPS systems, and for industrial processes.

Mode of operation

The transfer control device 3KC ATC5300 controls the transfer between the main and standby power supplies fully automatically, while incorporating set limit values and delay times. It detects fluctuations occurring in the main power supply quickly and switches to the standby power supply. The control device only switches to the standby power supply after it has ensured that the standby supply is delivering the required power supply quality. The devices switches back to the main power supply taking into consideration the set parameters once the required power supply quality is available again. If the standby power supply and/or the main power supply is fed by a generator, the control device also offers a wide range of settings, such as a generator lead time, generator delay time, and generator start test at specified times.

The transfer control device 3KC ATC5300 can control air circuit breakers, molded case circuit breakers, switch disconnectors or contactors. The circuit breakers are controlled via the related motorized operating mechanisms.

Setting parameters and monitoring with the SENTRON ATC software

In addition to operation and parameterization on-site, you can also monitor and set the parameters of the controller using the SENTRON ATC software. The software offers a high level of convenience and quick settings when connecting generators.

Measurement variables

The transfer control device 3KC ATC5300 gathers and monitors the following measured variables:

The advantages of the transfer control device 3KC ATC5300 at a glance:

  • Controls compact molded case circuit breakers MCCB, air circuit breakers ACB, switch disconnectors LBS, or contactors
  • Two measuring inputs for single-phase and multi-phase power supply systems • Possibility of switching from system to system, generator to network, system to generator and generator to generator
  • Direct measurement of three-phase industrial systems up to AC 400 Vph-N or AC 690 Vph-ph (no further costs for transformer, mounting or installation)
  • Two voltage supply units to cover all standard AC/DC voltage supplies, alternative supply via main and standby system possible
  • Low space requirements due to door installation and compact design
  • Two displays for monitoring the normal/standby system and displaying the phase and interlinked cable voltages
  • Setting control parameters for generator activation requirements
  • Calendar clock
  • 8 digital inputs, 6 of which are programmable and 7 relay outputs, 5 of which are programmable
  • 4 selectable operating modes: off, manual, automatic, test
  • Data, parameter and logged events (e. g. power failure, faults) remain accessible and unaltered, even after a power failure or restarting a device
  • Status display of the connected switches or contactors
  • Logging and statistical processing of occurring events possible
  • Easy system integration through integrated MODBUS interface (RTU and ASCII) i. e. into a power management system
  • The illuminated LED display makes reading measured values and parameters easy, even under unfavorable lighting conditions
  • Significant time savings when setting parameters and setting up the transfer control device 3KC ATC5300 via the SENTRON ATC programming software
  • Generator test run function for mandatory testing intervals
  • Command option for switching to the second set of protection parameters in the ETU76B (3WL air circuit breaker).
