Allen Bradley CAB6-300-EI Motor Contactor 300HP at 575VAC 340AMP at 600VAC

The Allen Bradley CAB6-300-EI is a robust three-pole motor contactor designed for heavy-duty industrial applications, particularly in controlling large electric motors. Manufactured under the Sprecher + Schuh CA6 series and branded by Allen Bradley (Rockwell Automation), this contactor offers reliable switching for motors up to 300 HP at 575 VAC and handles continuous currents up to 340 A at 600 VAC. It features electronic coil control (EI suffix) for efficient operation across a wide voltage range, reducing energy consumption and coil hum compared to traditional electromagnetic coils. Key advantages include high breaking capacity, compact design for space-constrained panels, and modular accessories for customization, such as auxiliary contacts or overload relays. Ideal for use in manufacturing, HVAC systems, pumps, and conveyor systems, it provides superior durability in harsh environments with IP20 protection. Drawbacks may include higher initial cost versus basic contactors and the need for compatible control voltages. Compared to similar products like Siemens 3TF or Schneider LC1, the CAB6-300-EI excels in longevity and integration with Rockwell PLC systems, making it a preferred choice for automated setups. Condition analysis from images indicates used/refurbished state with visible wear, test passed in 1999, and no major damage observed.
