Device description

Type 1 Surge Protective Device

Surge protective device intended to divert high-energy impulse currents and classified by the manufacturer as a Type 1 SPD.

A Type 1 surge protective device is used as part of an electrical installation's protection system against transient overvoltages and is designed to handle high-energy impulse currents.

One of the principal characteristics of this SPD type is the impulse discharge current Iimp. Additional characteristics may include impulse charge, specific energy, voltage protection level Up, modes of protection, and follow-current interrupt capability.

A Type 1 SPD may use spark-gap, varistor, or combined technology. Its electrical behaviour may be voltage-switching, voltage-limiting, or combined.

The design may include internal and thermal disconnectors, replaceable protective modules, status indication, and requirements for external backup protection.

Selection criteria include the electrical system, modes of protection, Iimp, Up, operating voltage, temporary overvoltages (TOV), connection configuration, backup protection, and declared compliance with applicable standards.

Components in this subcategory

This subcategory includes Type 1 surge protective devices with different pole arrangements, technologies, connection configurations, and impulse discharge current Iimp values.
