Eaton SPD160208Y2A – Type 2 Surge Protective Device

The Eaton SPD160208Y2A is a high-performance Type 2 surge protective device (SPD) engineered for installation at service entrances or sub-panels in 208Y/120V three-phase electrical systems. It provides reliable protection against transient overvoltages caused by lightning strikes, utility switching, or internal load switching, safeguarding sensitive electronic equipment and reducing downtime.

Robust Surge Protection

With a maximum surge current rating of 160 kA per phase (8/20 µs waveform), the SPD160208Y2A can handle severe transient events. Its thermally protected metal oxide varistor (MOV) technology ensures rapid response and long service life. The device is designed for shunt (parallel) connection to the power system, diverting surge energy safely to ground.

Key Features

• Type 2 Application: Suitable for fixed installation downstream of the main service disconnect, protecting distribution panels and connected loads.

• High Surge Capacity: 160 kA per phase (maximum) provides robust protection for commercial and industrial facilities.

• Voltage Configuration: Designed for 208Y/120V AC, 50/60 Hz, three-phase, four-wire plus ground systems.

• LED Status Indicators: Visual indication of protection status and end-of-life, simplifying maintenance.

• Compact Enclosure: NEMA 4X rated enclosure for indoor or outdoor mounting, resistant to dust, water, and corrosion.

• Compliance: Meets UL 1449 4th Edition and IEC 61643-11 standards for surge protective devices.
