The Schneider Electric Square D TVS8HEMA12SI is a Type 2 surge protective device engineered to safeguard electrical systems from transient overvoltages. This arrestor is designed for use in industrial environments where protection against lightning strikes and switching surges is critical, such as in power distribution panels and motor control centers.

Technical details

• Series: Square D TVS
• Model Number Encoding: The "8HEMA12SI" designation indicates specific performance characteristics. The "12" likely refers to a nominal voltage rating, and "SI" may denote a specific configuration or series variant.
• Surge Current Rating: Rated for 120 kA (kiloamperes) per pole, providing substantial protection against high-magnitude surges.
• Protection Mode: Designed for line-to-neutral, line-to-ground, and neutral-to-ground protection, offering comprehensive coverage within a three-phase system.
• Construction: Features a robust construction suitable for demanding industrial applications.
• Indicator: Includes a visual indicator for status monitoring.
• Application Voltage: Typically designed for systems operating at 480VAC nominal voltage, common in North American industrial settings. Buyers should verify exact voltage compatibility with the manufacturer's datasheet.

Applications & compatibility

This surge arrestor is commonly deployed in critical infrastructure and manufacturing facilities to protect sensitive electronic equipment and machinery. Applications include protecting variable frequency drives (VFDs), programmable logic controllers (PLCs), and other control system components in industries such as food and beverage processing, automotive manufacturing, and water treatment plants.
