FAQs
To install the PX3-3Y101, mount the unit in a suitable panel ahead of critical loads in a three-phase 120/208 V system. Use the catalog number PX3-3Y101 for ordering, connect per the wiring diagram, and verify proper grounding. The device’s compact 2.5 in depth and 2.9 in width simplify enclosure fitment and reduce panel crowding, speeding commissioning.
With a 50 kAIC surge rating, the PX3-3Y101 absorbs and clamps transient energy before it reaches sensitive loads such as drives, PLCs, and sensors. This capability minimizes voltage excursions, preserves equipment life, and supports continuous operation in environments prone to lightning, switching transients, or grid disturbances—critical for uptime in manufacturing and data centers.
Yes. The PX3-3Y101 is designed to integrate into Eaton’s protection ecosystem and is listed with a standard 120/208 V wye three-phase configuration. It can be used alongside other PX3 family devices within the same panel or enclosure, simplifying procurement and stocking while ensuring consistent protection characteristics across the installation.
Certification details aren’t listed in the provided data. In practice, consult Eaton’s product specifications for CE marking, IP enclosure rating, and relevant safety standards in your region. When selecting a surge protector for critical equipment, verify compliance with your facility’s electrical codes, industry standards, and your project’s lifecycle requirements.
Investing in the PX3-3Y101 yields measurable uptime gains and reduced maintenance costs by limiting transient damage to motor drives, controllers, and sensors. Fewer unplanned outages translate to increased production throughput, lower spare part usage, and longer service intervals for protected equipment—key factors in a competitive, uptime-driven manufacturing environment.
