Product Description

This high-performance Type 2 AC Surge Protection Device (SPD) offers robust defense against voltage spikes and transient surges in electrical systems. Designed for commercial and industrial applications, it provides 40kA maximum discharge capacity (Imax) with a 20kA nominal current rating (In), ensuring reliable protection for your valuable equipment. The SPD features varistor-based voltage limiting technology combined with a low residual voltage design, effectively clamping dangerous overvoltages before they can damage connected devices. Its pluggable modular design allows for quick replacement without system downtime, while integrated thermal disconnectors provide fail-safe operation. Visual status indicators (Green/Red) offer at-a-glance monitoring of operational state, with optional remote signaling capability for integration into monitoring systems.

Engineered for easy installation, the unit mounts on standard 35mm DIN rails, making it compatible with most electrical panels. The product complies with international standards including IEC 61643-11, EN 61643-11, and GB/T 18802.11, and carries CE, TÜV, UKCA, and CB certifications for global acceptance. Ideal for protecting electrical distribution systems against lightning strikes and power surges, this SPD combines advanced protection technology with user-friendly features for optimal performance and maintenance convenience. Its durable construction ensures long-term reliability in demanding environments.

A high-performance Type 2 AC surge protector designed to safeguard your electrical systems from power surges.
