Westinghouse MG-6 Multi Contact Auxiliary Relay 1163801

The Westinghouse MG-6 Multi Contact Auxiliary Relay, catalog number 1163801, is a robust, electromechanical relay designed for use in protective relaying systems within power distribution and control applications. This model operates on a 125VDC coil and features multiple contacts for switching and control purposes, making it suitable for industrial environments such as substations, motor controls, and automation systems. Key benefits include high reliability in high-voltage scenarios, durable construction for long-term use, and compatibility with legacy Westinghouse protective relay setups. However, as an older model (likely from the mid-20th century), it may require maintenance or refurbishment, and drawbacks include potential obsolescence, higher energy consumption compared to modern solid-state relays, and limited availability of parts. Advantages over similar products like contemporary digital relays include simplicity, no need for programming, and proven performance in harsh conditions without electronic failures. Applications span electrical interlocking, alarm systems, and auxiliary functions in power grids. Based on provided images, this unit appears to be in used condition, possibly for parts, with visible wear, exposed coil, and no attached accessories. It offers a cost-effective solution for maintaining vintage equipment but may not meet current efficiency standards.
