1. Introduction The Beckwith M-2001B is a legendary electromechanical relay, known for its robustness and reliability in generator protection schemes. While modern microprocessor-based relays dominate new installations, thousands of M-2001B units remain in active service worldwide. The Beckwith M-2001B Manual is the essential document for operating, testing, and maintaining this specific relay model.
For engineers working on legacy systems, having a copy of this manual is non-negotiable. While modern relays offer more features, the M-2001B’s simplicity and toughness remain unmatched in certain industrial environments. Article prepared for electrical protection engineers and maintenance technicians. Always follow the original manufacturer’s safety warnings when working with energized relays.
This allows the relay to be insensitive to external faults (high restraint) but responsive to internal faults (high operating current).
