Cutler-Hammer FD3020BU Molded Case Circuit Breaker

Cutler-Hammer FD3020BU is a three-pole molded case circuit breaker rated for 20 amps at 600 volts. This protection device interrupts current during overloads or fault conditions to safeguard wiring and connected equipment in electrical distribution panels and industrial or commercial installations. Designed for three-phase systems, the FD3020BU offers compact, enclosed overcurrent protection for circuits requiring a 20 A rating and a 600 V maximum, making it a fitting choice when a standard 3P, 20A MCCB is specified for panel boards and equipment safety. In typical electrical distributions, such a device serves as the main or branch protection point, enabling safe shutdown of circuits and helping to maintain system reliability in varying load conditions. The FD3020BU is a purpose-built component within the Cutler-Hammer molded case line, selected where robust, dependable interruption at 20 A and 600 V is needed.
