FAQs

The unit is a three-pole molded case circuit breaker designed for three-phase feeders. It supports screw terminals and metric tapped conductors, enabling straightforward wiring in standard MCCB enclosures and dense panels. This simplifies installations and reduces commissioning time for panel builders.
It is rated for 800 A with thermal magnetic trip, including adjustable thermal and adjustable magnetic settings. It provides a 70 kA short-circuit withstand rating, offering robust protection against high-energy faults in industrial power distribution.
The PDC43N0800TAAS is primarily specified for three-phase feeder protection in Power Defense MCCB applications. While it can protect motor feeder circuits, motor protection often requires evaluating start-up surge and curve characteristics; consult Eaton’s application notes to ensure alignment with motor loads and AC-3/AC-1 duty requirements.
The PDC43N0800TAAS is certified to IEC/CCC standards, supporting global deployment in compliant facilities. Eaton also provides EU declarations of conformity for Power Defense MCCBs, aiding regulatory assessments and product qualification in international projects.
Adjustable thermal and magnetic trips reduce nuisance trips and fine-tune protection for evolving load profiles, delivering lower downtime. Screw terminals and metric taps speed wiring and field servicing, while the robust Power Defense design minimizes replacements in demanding environments, contributing to lower lifecycle costs.
