Overview

The SolaHD HSP-121BT1RU Three-Stage Power Line Protector is a compact, industrial-grade surge suppression device designed to safeguard sensitive equipment from transient voltage spikes in demanding environments. Operating at 120 VAC with a 15 A current rating, this protector delivers reliable performance within a 47–63 Hz frequency range, making it compatible with standard industrial power systems. Its three-stage clamping mechanism limits transient voltage to a maximum of 325 VAC, ensuring rapid suppression of over-voltage events while maintaining circuit integrity. The device handles peak surge currents up to 13 kA per mode and 26 kA per phase, providing robust protection against lightning-induced surges and switching transients. With compliance to UNSPSC code 43222901, the HSP-121BT1RU is ideal for integration into motor control panels, PLCs, and industrial automation systems. Its compact design allows for easy installation in standard industrial enclosures, reducing downtime and simplifying maintenance. Manufactured by SolaHD, a trusted name in power protection solutions, this protector enhances the longevity of critical infrastructure by preventing damage from voltage spikes. Key features include parallel token generation for faster response times and a durable construction that withstands harsh operating conditions. Whether deployed in factories, warehouses, or utility facilities, the HSP-121BT1RU ensures uninterrupted operation and operational continuity for sensitive electronic equipment.
