Information About 500-GOB930

The Allen Bradley 500-GOB930 is a high-capacity contactor designed for industrial electrical control applications, particularly in environments requiring reliable switching of large electrical loads. Falling under the Contactors & Starters category, this device is specifically engineered to handle high current demands, providing robust performance in motor control, power distribution, and other heavy-duty switching applications. As a contactor, it operates by opening and closing electrical circuits, thereby controlling the flow of electrical power to motors, heaters, lighting systems, and other large electrical devices.

This particular model, part number 500-GOB930, has a current rating of 540 amps, which makes it suitable for controlling high-power circuits in industrial automation systems. The device is classified as a NEMA Size 6 contactor, indicating its capacity to handle significant loads and its compatibility with large-scale industrial equipment. The contactor is designed to withstand and control high peak inrush currents, with a maximum inrush current rating of 6326 amps, ensuring reliable performance even during startup surges common in motor control applications.

The 500-GOB930 is equipped with an open enclosure design. This open-frame construction is typical for industrial contactors installed within protective electrical enclosures or panels, where it can be easily integrated into existing control systems. The open design allows for better heat dissipation during operation, improving the longevity and reliability of the device under heavy load conditions. For environments requiring additional protection, external enclosures may be used to house the contactor to meet specific application safety standards.

The contactor operates on a coil voltage of 440/480 volts AC, which is a standard voltage range in industrial settings. The coil energizes the contactor to close or open the electrical circuit, enabling or disabling the flow of electricity to connected loads. This coil voltage specification allows the 500-GOB930 to be used in a variety of industrial control systems powered by medium-voltage AC supplies, offering flexibility for integration into different plant environments.

A key feature of the 500-GOB930 is its three-pole design, which enables the control of three-phase electrical loads. Three-phase power is common in industrial applications due to its efficiency and ability to deliver large amounts of power to motors and other high-demand equipment. The three-pole configuration ensures that the contactor can safely and effectively manage the operation of three-phase motors or other similar loads, providing reliable performance even under continuous operation or in high-demand situations.

Additionally, the 500-GOB930 is equipped with auxiliary contacts, which provide additional switching capabilities for secondary circuits. These auxiliary contacts can be used to control secondary functions, such as signaling, interlocking, or triggering additional devices in a control system. The inclusion of auxiliary contacts adds flexibility to the overall system design, allowing the contactor to perform multiple control functions simultaneously, thereby enhancing the overall control capabilities of the electrical system.

The wiring for the 500-GOB930 is configured as feedthrough, meaning that the wiring connections for the input and output circuits pass directly through the contactor. This design simplifies installation and maintenance by providing clear and direct wiring paths, which also helps to reduce the overall complexity of the control panel layout. The feedthrough wiring configuration is ideal for applications where space is limited and efficient wiring management is a priority.

In terms of durability, the 500-GOB930 boasts an impressive mechanical life of 5 million operations. This high mechanical lifespan makes it a reliable and long-lasting solution for industrial environments that require frequent switching operations. The extended operational life reduces the need for maintenance or replacement over time, contributing to lower overall operating costs and minimizing downtime in critical applications.

The 500-GOB930 is designed to handle demanding industrial conditions, making it an ideal choice for applications in sectors such as manufacturing, mining, utilities, and heavy industry. Its ability to manage high currents and inrush loads, combined with its durable mechanical construction, ensures that it can reliably perform under continuous operation and in environments with harsh conditions.

In summary, the Allen Bradley 500-GOB930 contactor is a high-performance electrical switching device designed for industrial applications requiring the control of large electrical loads. With a current rating of 540 amps, a NEMA Size 6 classification, and the ability to handle peak inrush currents of up to 6326 amps, this contactor is built to manage demanding electrical loads reliably. Its open enclosure design, three-pole configuration, auxiliary contacts, and feedthrough wiring provide flexibility for a wide range of industrial uses. With a mechanical life of 5 million operations, the 500-GOB930 offers long-term durability and reliable performance, making it a valuable component in any industrial control system.
