FAQs

The PDC44N0800TAAS is built as a four-pole molded case circuit breaker designed for standard MCCB enclosures. It uses screw terminals and metric tapped conductors, with dimensions that fit typical frame sizes in Power Defense applications. This compatibility simplifies retrofits and ensures reliable field wiring while delivering 800 A rated protection for main feeders.
This MCCB combines thermal magnetic trip with adjustable thermal and adjustable magnetic settings to tailor protection to your load profile. You can configure the thermal setting to accommodate motor inrush and heat dissipation, while the magnetic setting adjusts for short-circuit conditions. This flexibility reduces nuisance trips and improves protection accuracy for mixed-load panels.
Ideal for large distribution panels, switchgear, and power distribution centers in manufacturing, process industries, and data centers. Its four-pole configuration with 100% neutral protection makes it especially suitable for networks where balanced phase protection and reliable fault isolation are critical, such as motor control centers and critical process lines.
The device carries CE conformity under EU Declaration of Conformity and IEC/CCC certification, as documented in Eaton's downloadable materials. The EU Declaration of Conformity and related specification sheets are available in the product downloads, enabling quick compliance checks for regional electrical standards.
By delivering reliable thermal magnetic protection with adjustable trip settings, the PDC44N0800TAAS reduces downtime from nuisance trips and extends equipment life. Its robust wiring terminals and standardized dimensions lower installation costs, while CE/IEC/CCC compliance simplifies audits, contributing to a faster project return on investment and long-term operating efficiency.
