The Allen-Bradley Model 80026-508-08-R is a versatile and reliable contactor offered by Rockwell Automation. This contactor is designed for use in various industrial automation applications, providing reliable control of electrical loads up to 20 amperes and 240 volts.
The 80026-508-08-R contactor features a robust construction with a copper-bonded contact system that ensures long-lasting performance and minimal wear. The copper-bonded contacts are fused directly to the contactor body, providing superior conductivity and reducing the possibility of arcing and contact welding.
The contactor also includes a built-in overload relay, which helps protect the contactor and the connected load from overcurrent conditions. The overload relay is adjustable, allowing users to set the trip current to their specific application requirements.
The 80026-508-08-R contactor is available in several configurations, including normally open (NO), normally closed (NC), and changeover (CO). The changeover configuration allows the contactor to switch between two loads, making it a popular choice for applications that require load transfer or redundancy.
The contactor also includes a built-in coil, which simplifies wiring and installation. The coil can be energized from an external source or from the contactor itself, depending on the application requirements. The contactor is also available in a variety of mounting configurations, including DIN rail, surface, and panel mount.
The 80026-508-08-R contactor is designed to operate in harsh industrial environments, with a temperature range of -40 C to 70 C (-40 F to 158 F). The contactor is also UL and CSA certified, ensuring compliance with various safety standards.
In summary, the Allen-Bradley Model 80026-508-08-R contactor is a reliable and versatile solution for controlling electrical loads in industrial automation applications. Its robust construction, adjustable overload relay, and availability in various configurations make it a popular choice for a wide range of applications.
