ABB SI-Unit Fuse Module POK 71 H&B Contronic

ABB SI-Unit Fuse Module POK 71 H&B Contronic

Basic information

Product name and number: ABB SI-Unit Fuse Module POK 71 H&B Contronic, where ‘POK 71’ is the specific number of the product in the Contronic series jointly produced by ABB and Hartmann & Braun (H&B). It is used to accurately identify the fuse module.

Series and compatibility: Belonging to the H&B Contronic series, it is designed to have good compatibility with other devices in the series, and can work with controllers, operator panels, power modules and other devices in the Contronic series to build a complete industrial automation control system.

Performance Features

Fuse Function: As a fuse module, its core function is to cut off the circuit through the fusing of the fuse when the current in the circuit is too large, so as to protect the equipment and components connected to the circuit from short-circuit currents, overload currents and other fault currents, and to ensure the safety and reliability of the system.

SI-Unit Integration: SI-Unit (International System of Units) is integrated, which can work better with the equipment or system that adopts the International System of Units (SI) for measurement and control, facilitating parameter setting, monitoring and control under a unified standard of measurement, and improving the overall coordination and accuracy of the system.

Signal transmission and indication: the module can not only realise the basic protection function of the fuse, but also has the function of signal transmission and indication. When the fuse breaks, it can send a corresponding signal to the control system in order to promptly notify the operator or the automation system that a fuse action event has occurred. At the same time, the module may be equipped with an indicator light, intuitively show the working status of the fuse, such as the indicator light is on during normal operation, and the indicator light is off or changes to another colour after the fuse is blown, which is convenient for the site personnel to quickly understand the status of the fuse.

Reliability and Stability: Adopting high quality materials and advanced manufacturing process to ensure stable and reliable operation under various industrial environment conditions. With good anti-vibration, anti-shock, temperature change and corrosion resistance, it can adapt to harsh industrial environments, keep its performance unchanged for a long time, and reduce failures and malfunctions caused by environmental factors.

Application Fields

Industrial automation production line: In automobile manufacturing, electronic manufacturing, food processing and other types of industrial automation production line, used to protect key equipment and control circuits. For example, installing the fuse module in the motor control circuit, sensor power supply circuit, PLC input/output circuit, etc. of the automated production line can effectively prevent equipment damage and production interruption caused by circuit failure, ensure the stable operation of the production line, and improve production efficiency and product quality.

Process control system: In the chemical, petroleum, pharmaceutical and other process control fields, as an important protection element used in a variety of process control equipment and systems. Such as chemical production in the reactor temperature control system, flow control system, petroleum refining in the distillation tower pressure control system, etc., when there is an abnormal current in the system, POK 71 fuse module can quickly cut off the circuit to avoid the expansion of the fault, to ensure that the production process is safe and stable, but also for the maintenance personnel to provide a clear indication of the fault, easy to quickly locate and eliminate the fault.

Intelligent Buildings and Energy Management Systems: In the electrical systems of intelligent buildings, they can be used to protect the circuit safety of lighting systems, air-conditioning systems, lift control systems and so on. In addition, in the energy management system, it protects the circuits of energy metering equipment, monitoring equipment, etc., to prevent circuit failures from affecting the accurate collection of energy data and the normal operation of the system, and to improve the energy utilisation efficiency and management level of intelligent buildings.
