Cutler-Hammer FDB2050 Molded Case Circuit Breaker

Cutler-Hammer FDB2050 is a two-pole molded case circuit breaker rated for 50 amperes and up to 600 V AC. This MCCB carries the model designation FDB2050 and is part of the Cutler-Hammer line of molded case protective devices. It is designed to provide overcurrent protection for circuits in electrical distribution systems, typically installed in panelboards or equipment enclosures that accept molded case breakers. With a 2-pole configuration, it protects a pair of conductors within the circuit, while the 50 A rating indicates the maximum continuous operating current under standard conditions before tripping. The 600 V AC maximum voltage rating specifies the highest voltage at which the device is intended to operate in typical AC power distribution. As a Cutler-Hammer product, this breaker is aligned with common industrial and commercial electrical installation practices that require reliable, interchangeable protection devices within compatible panels. The FDB2050 specification is concise and clear, enabling quick matching to system requirements for amperage, voltage, and pole count in projects that call for a standard 50 A, 600 V AC molded case breaker.
