The KPTB18-32PSA71 IEC logic contactor is a device used frequently for control and switching purposes in electrical circuits. It is designed to control larger currents than other types of contactors and can also provide isolation between different electrical power supply links. In this article, we will take a closer look at the application fields and working principle of the KPTB18-32PSA71 IEC logic contactor.

The KPTB18-32PSA71 IEC logic contactor is a three-pole contactor that can be used with IEC standard logic control circuits such as PLCs or computers. It is rated for the control of up to 18 Amps AC1 at a voltage up to 440 V. This type of contactor is used for controlling larger currents than those typically controlled by conventional control relays. It is suitable for switching on/off of electrical circuits, for both industrial and domestic applications.

The working principle of the KPTB18-32PSA71 logic contactor is simple and effective. When the coil is energized, it magnetizes the moving armature which in turn is attracted to the fixed armature. This draws the three-pole switchpoints together and the circuit is closed. When the coil is de-energized, the attraction between the moving and fixed armatures is removed and the circuit is opened. This operating principle makes the KPTB18-32PSA71 ideal for a range of switching applications such as motor starters, transformer switching, and contactor combinations.

The KPTB18-32PSA71 can be used in a variety of application fields. It is suitable for use in domestic lighting and heating systems, process automation systems, motor control and switching systems, and many more. Its high current capacity and durable design make it an ideal choice for installations with frequent switching operations. The KPTB18-32PSA71 can also be connected in combination with other contactors to create larger low voltage switching systems.

In summary, the KPTB18-32PSA71 IEC logic contactor is a highly versatile device capable of controlling large amounts of current. It is suitable for a variety of application fields including domestic and industrial control and switching systems. Its simple and effective working principle ensures reliable and safe current switching operations.
