Westinghouse 2-4P N Relay 440V/60CY S-1720613

The Westinghouse 2-4P N Relay is a vintage industrial relay designed for control and protection applications in electrical systems. Rated for 440V at 60 cycles (Hz), this 2-4 pole normally open (N) relay is suitable for use in motor control, switchgear, and power distribution systems. It features a robust, wax-coated cylindrical design that provides insulation and protection against environmental factors, making it ideal for harsh industrial environments such as manufacturing plants, utilities, and marine applications. Key benefits include reliable switching performance, high voltage tolerance, and durability, with advantages over modern relays in terms of simplicity and compatibility with legacy systems. However, drawbacks may include limited availability of parts, potential obsolescence, and the need for periodic maintenance due to its age. This specific unit, serial number S-1720613, appears to be new old stock (NOS) based on labeling, though images show some surface dirt and aging, indicating it has been in storage. It offers precise control for AC circuits, with applications in overload protection and automation. Compared to similar products like ABB or Siemens relays, it provides cost-effective retrofitting for older installations but may lack advanced digital features. For detailed model decoding, refer to Westinghouse legacy documentation; the '2-4P' likely denotes pole configuration, and 'N' indicates normally open contacts.
