The Type 1 Surge Protective Device is for lightning and surge protection of single-phase TT/TN (220V/230V AC) networks. Located at the main power entry, it discharges high energy spikes to the ground for protection of the power distribution system. Whole House Surge Protector controls severe overvoltages. Scalable for extreme applications such as healthcare systems and computer rooms, Line offers Class 2 and Class 3 SPD compatibility.
Type 1 Surge Protective Device
A Type 1 SPD is meant to protect electrical systems from voltage transient risks associated with lightning strikes or power surges. Connected to the main power entry point, and capable of delivering maximum protection to the system, increases the reliability and safety of the system. It is crucial for use in varied industries and businesses since; it shields delicate equipment from damage and is cost-effective regarding maintenance.
How it works?
Type 1 SPD cleaves huge voltage spikes in the electrical systems and discharges them to the ground. Most commonly, it is fitted at the point where the main power supply enters a building and its purpose is to protect both the devices connected and the electrical installation from transient overvoltage.
Features
- Surge Protective Device (SPD): The first form of SPD is capable of protecting against high energy bypass and thus can be deployed in both interior and exterior facilities. It safeguards electrical equipment from the risks that accompany overvoltage.
- Collaboration with Other SPDs: Used together with Type 2 and Type 3 SPDs, it creates the overall protection system of electrical infrastructure, enhancing safety and reliability of equipment.

Installation Location
Usually mounted at the power point of utilization, often by the main distribution board or where the electric meter is situated. This placement guarantees maximum protection against surges that may find their way into the electrical system from external sources.
Scope of application
- Applications: Used in buildings and equipment that need more protection, such as hospitals, industries, and computer centers.
- Standards Compliance: Aiming at IEC 61643 and UL specifications, which guarantee operation and protection of important electrical equipment from overvoltage and surge.
