Lot of 8 - Furnas 52BAJ Series D Oil Tight NC Contact Block

The Furnas 52BAJ Series D Oil Tight NC Contact Block is a robust, normally closed auxiliary contact designed for use in industrial control systems, particularly with pushbutton stations, selector switches, and pilot devices. Manufactured by Furnas Electric Company (now part of Siemens), this contact block is rated for NEMA A600 (AC) and Q600 (DC) applications, making it suitable for heavy-duty environments where oil, dust, and moisture resistance is critical. Key features include a sealed, oil-tight construction that prevents contamination, ensuring reliable performance in harsh industrial settings such as manufacturing plants, oil refineries, and automation lines. Advantages over similar products include its compatibility with 30mm operators, high electrical ratings for demanding loads, and durable build that extends service life compared to standard contact blocks. Benefits encompass easy installation via screw terminals, enhanced safety through reliable switching, and reduced downtime due to its rugged design. Drawbacks may include limited availability of parts since Furnas branding has been phased out, potentially requiring cross-referencing to Siemens equivalents like 3SB3 series. This lot of 8 units appears new or unused based on packaging, ideal for maintenance stockpiles or system upgrades. Applications range from motor controls to signaling circuits, offering precise control in NEMA-rated enclosures.
