Eaton CD3-Z369-1 Three-Phase Molded Case Circuit Breaker

The Eaton CD3-Z369-1 functions as a dedicated three-phase molded case circuit breaker engineered to safeguard downstream electrical systems and motors with a sustained rated current capacity of 90 amps delivered through three independent poles to handle balanced load distribution requirements efficiently. Produced by Eaton Heinemann Electric, this unit manages significant load interruptions and short-circuit faults within industrial power distribution architectures that require synchronized three-phase protection for reliable operational continuity in demanding industrial factory environments. The associated National Stock Number 5925-01-128-6405 validates the component for precise logistical identification in government procurement scenarios, allowing supply clerks to locate the specific part required for scheduled maintenance cycles and regulatory compliance tracking. Service technicians install this specific breaker configuration into existing electrical panelboards to replace damaged units, ensuring the robust molded case enclosure properly contains potential electrical arcs and maintains vital separation between live terminals during mandatory emergency disconnection events for overall system safety and personnel protection.
