Eaton PX1-3Y201 Surge Protective Device - 50 kAIC
Part Number: PX1-3Y201
Quick Summary
The Eaton PX1 surge protective device provides fast, reliable protection for three-phase electrical systems in industrial facilities. It helps prevent costly equipment damage from transient surges and reduces unplanned downtime by diverting surge energy away from sensitive components. While the data sheet lists the PX1-3Y201 at 50 kAIC energy handling and 277/480 V (wye) operation, the design supports quick field installation in panelboards and MCCs. Certifications and safety standards commonly referenced for this class support reliable performance in harsh environments; expect CE or equivalent compliance and robust enclosure protection in typical applications. Using PX1 protection delivers measurable value through improved equipment life, safer operation, and easier procurement for engineered systems.

High-energy protection with a 50 kAIC rating delivers robust defense against sudden transients, reducing the likelihood of insulation damage and unexpected outages. This capability translates into measurable uptime gains and lower replacement costs for critical drives, PLCs, and motors. In data centers, manufacturing lines, and plant MCCs, the PX1-3Y201 shields power quality without limiting normal operation. Three-phase, 277/480 V wye configuration ensures compatibility with common industrial feeders, simplifying panelboard integration and reducing wiring complexity. The result is faster installation, fewer termination errors, and consistent performance across machines with similar power architectures. Engineers can specify the PX1 in new builds and retrofits with confidence that standard industrial distributions will be protected. Compact form factor (2.5 in depth, 4.8 in height, 2.9 in width) and a weight of 1.25 lb make it suitable for tight spaces and retrofit projects. Lightweight, modular protection improves serviceability during maintenance outages and supports clean enclosures in crowded electrical rooms. The PX1 series is designed for straightforward mounting and compatibility with standard panelboard footprints. Installation and procurement advantages include a clear catalog number PX1-3Y201 and universal UPC for inventory control. The device integrates with Eaton's PX1 family, offering a consistent protection strategy across sites and simplified spare-part planning. Industry professionals benefit from a trusted brand’s support network and readily accessible documentation to speed project delivery. Addressing common objections, the PX1-3Y201 provides high-energy protection without a bulky footprint, offering cost-efficient surge protection that minimizes downtime. Its 277/480 V capability helps avoid over- or under-protection when serving mixed loads, and the 50 kAIC rating supports future capacity expansion as plants scale.

FAQs
The PX1-3Y201 is designed for straightforward field installation in common industrial panelboards and motor control centers. Begin with confirming 277/480 V wye service and available mounting space. Mount the device in a supplied enclosure footprint, connect line-side and load-side conductors per the PX1 datasheet, and verify proper grounding. Use the catalog number PX1-3Y201 for procurement and ensure the enclosure has adequate clearance for heat dissipation and safe maintenance access. Field checks should include voltage confirmation and surge alignment prior to full-load operation.
A 50 kAIC rating indicates the device can safely absorb or divert surge energy equivalent to 50 kiloampere instantaneous current at the point of protection. In practical terms, this level supports protection against high-energy transients typical in industrial environments, safeguarding sensitive equipment like PLCs, drives, and motors. This rating contributes to reduced insulation stress, fewer component failures, and extended equipment life when used in appropriately rated systems.
Yes, the PX1-3Y201 is well-suited for critical loads found in data centers and motor control centers. Its three-phase 277/480 V wye configuration aligns with common facility power structures, and the 50 kAIC protection provides robust defense against transient events. For data centers, this helps maintain uptime and protects power distribution hardware; for MCCs, it supports reliable motor operation and reduces unscheduled maintenance.
Typical evaluations for surge protective devices in this class reference international safety and electrical standards, and verification is done via the manufacturer’s datasheet and certificate documents. For PX1-3Y201, consult Eaton’s official documentation to confirm specific certifications (for example CE marking and safety test results) and the exact standard references. When selecting, request the latest test reports and ensure the installation site requires the documented compliance levels.
Surge protective devices like PX1-3Y201 require periodic visual inspection and integrity checks as part of a preventive maintenance program. Many sites replace protection devices after sustained surge events or at scheduled intervals aligned with electrical maintenance cycles. The ROI comes from reduced unplanned downtime, less equipment damage, and lower repair costs, plus improved system reliability and predictable project timelines due to a proven, trusted protection solution from Eaton.
