Therefore, a warning and a tripping threshold can be set in the SIMOCODE-DP. KTY detectors incorporate a resistance curve which rises linearly with the temperature. Apart from binary thermistor detectors, SIMOCODE-DP also evaluates analogous (KTY) thermistor detectors. evaluation devices are required, thus saving space in the switchboard. The temperature is measured directly at the motor windings via a PTC or NTC thermistor detector and is evaluated by SIMOCODE-DP No additional. Built-in thermistor motor protection Thermistor motor protection is used for the thermal protection of motors. The tripping time can be finely adjusted to the start-up conditions and the utilization of the motors can be optimized. Finely adjustable adaptation to start-up conditions It is possible to select a tripping class in six steps from CLASS 5 to CLASS 30. The 3UF50 basic unit can also be used as an autonomous, solid-state overload relay for motor protection. Overload protection SIMOCODE-DP protects the load, independent of the automation level, against overload, phase failure and current imbalance. Unbalanced current consumption, phase failure or a stalled rotor are some of the possible causes of overloading. Thermistor-Type Motor Protection Without CompromiseД®lectrical equipment such as AC motors and transformers need protection against excessive heating. The existing motor protection functions (overload, phase failure and current imbalance detection) are supplemented by thermistor motor protection and earthfault monitoring.Д¬ommunicationscapable low-voltage switchgear SIMOCODE-DP SIMOCODE-DP is capable to realize several control functions, like direct-, reversing-, star-delta starters and to implement user-specific controls by using the freely assignable inputs and outputs and the built-in truth tables, timers and counters. In all that industries it is used for an enormous variety of applications. SIMOCODE also provides the communication between the master level and the automation level by its integrated PROFIBUS-DP interface.

Intelligent load feeders SIMOCODE-DP also helps ensure that high-availability systems such as coal, gas and hydroelectric plants run around the clock. There it has proved its reliability for more than five years. Instance in the paper, chemical, textile, steel, oil and gas, waterwork plants, cement, petrochemical, shipbuilding, food and consumer goods industries. The system SIMOCODE-DP protects and controls load feeders for As it is widely used in the process and others industries, you can find it all over the world. This places a wide range of requirements on such an intelligent field device. The fact that this state-of-the-art technology is being increasingly used reflects the requirement for increased plant availability but at the same time, cost savings during the construction and commissioning of a plant and its operation. It represents the intelligent link between the motor feeder and the process control system. SIMOCODE-DP is a tried and tested system Increasingly, the communicationscapable SIMOCODE-DP 3UF5 motor protection and control device is being successfully used worldwide in lowvoltage switchgear systems. The new communications-capable SIMOCODE-DP 3UF5 Siemens Motor Protection and Control Device - Decentralized Peripherals makes life easier for the system designer.

To meet all these requirements, the system designer has to have extensive knowledge of the complete range of low-voltage switchgear. Every motor has optimum protection, the scope of wiring is as small as possible and spares must not mean high storage costs.

A system should, for example, be compact, intelligent and powerful. There is less and less time in between ordering and the start-up of a system however, the requirements made on motor feeders are increasing.
