50 kAIC surge current rating delivers high-energy transient absorption for critical loads. This capability reduces insulation stress on transformers, drives, and control electronics, diminishing the likelihood of insulation breakdown or equipment misoperation that disrupts production. In practice, it supports protection for motor drives, PLCs, and panelboard assemblies across varied line conditions in manufacturing lines and process facilities. Three-phase protection across a 120/208V wye supply ensures synchronized clamping on all lines, preventing imbalanced transients that can degrade sensors and power electronics. Balanced protection minimizes phase-to-phase excursions, reducing nuisance trips and extending the life of connected loads. This arrangement is especially valuable in OEM-controlled panels, machine control rooms, and distribution blocks where uptime and reliability directly impact throughput. The PX1-3Y101 uses a compact footprint (2.5 in depth, 4.8 in height, 2.9 in width) and a modest 1.25 lb weight. That small form factor simplifies retrofits and enables installation in crowded panels or retrofit projects without extensive enclosure redesign. Its size also supports quicker commissioning, streamlined wiring, and compatibility with standard panel hardware used in industrial environments. As part of the Eaton PX1 series, PX1-3Y101 integrates with Eaton protection schemes and the broader SPD portfolio. This compatibility reduces procurement complexity and encourages a unified protection strategy across multiple machines, lines, and facilities. Wiring and footprint are aligned with common industrial practices, facilitating straightforward installation in new builds and upgrades. Deploying the PX1-3Y101 translates to measurable reliability gains, including fewer unplanned outages and lower spare-part consumption. The device helps protect power electronics, relays, and controls, driving improved process stability and predictability. Over time, this supports reduced maintenance costs and a clearer path to achieving uptime targets in critical production lines. Installation and accessibility considerations include ensuring adequate clearance for venting and service access, with the 2.5 inch depth allowing denser panel layouts. For engineers, the result is faster project timelines and lower field-change risk during upgrades.

FAQs
Yes. PX1-3Y101 is designed for use in 120/208V three-phase panels and industrial control environments. Its compact footprint (2.5 in deep, 4.8 in high, 2.9 in wide) and ~1.25 lb weight help it fit within standard panel enclosures. Follow the catalog guidelines for mounting, wiring, and connection to ensure balanced protection across all phases.
The defining specification is a 50 kAIC surge current rating, enabling high-energy transient absorption to protect downstream equipment. It protects 120/208V three-phase systems, safeguarding motor drives, PLCs, sensors, and control electronics from dangerous voltage surges while reducing the likelihood of nuisance trips and equipment damage.
Yes. The device is designed for three-phase power in industrial settings and is particularly effective for motor drives, drives-enabled machinery, and plant process controls. By stabilizing voltage transients at the panel, it supports smoother operation, reduces wear on drives, and enhances overall line reliability in manufacturing environments.
Look for CE marking and IEC/EN safety compliance as standard expectations for PX1 devices. Depending on your region, verify IP enclosure protection and SIL readiness requirements within your safety architecture. Always confirm current regional certifications with the supplier or catalog documentation for batch-specific compliance.
Deploying PX1-3Y101 reduces unplanned downtime, protects critical power electronics, and lowers spare-part usage by mitigating surge-related damage. The resulting uptime and reliability translate to higher production throughput, improved process stability, and a clearer pathway to meeting maintenance targets across high-demand production lines.
