Type 1 Whole-Facility Surge Protection — 240kA Per Phase

The PSP 120/240VAC 1-Phase Type 1 SPD delivers permanent, service-entrance-level surge protection for residential and light commercial facilities. Rated at 240kA surge current capacity, this unit is engineered to intercept and divert the most destructive transient overvoltages before they reach your equipment — including direct lightning strike energy.

Why Choose This Type 1 SPD?

• 240kA surge current rating (per phase) — Industry-leading capacity to handle catastrophic surge events, including indirect lightning strikes
• Type 1 rated (permanently connected) — Installs ahead of the main disconnect; no disconnect required between the utility and the SPD
• 120/240VAC 1-Phase compatibility — Designed for standard single-phase residential and light commercial service entrances
• ANSI/UL 1449 4th Edition listed — Meets the latest safety and performance standards for surge protective devices
• Low clamping voltage — Minimizes let-through voltage to protect sensitive downstream electronics and equipment
• Thermal disconnect with visual indicator — Built-in protection against overheating with a status indicator for easy maintenance checks
• Compact, DIN-rail or panel-mount design — Fits cleanly inside standard electrical enclosures for a professional installation

Ideal For:

Residential service entrances, light commercial facilities, critical equipment protection, generator-fed panels, and any single-phase application requiring maximum upstream surge defense.

Installation: Connects at the service entrance ahead of the main breaker. Type 1 classification means it can be installed without an upstream disconnect, making it the first line of defense against utility-side surges and lightning transients.

Protection You Can Count On: PSP Products is a trusted manufacturer of surge protective devices built to ANSI/UL 1449 standards, delivering reliable transient voltage suppression for facilities where downtime and equipment damage are not an option.
