Type 1 component assembly is a Type 4 SPD that once installed inside another piece of equipment would be tested as a Type 1 SPD (would not require external overcurrent protection).
Welcome to Eaton’s Bussmann series Selecting Protective Devices (SPD) handbook. This reference document is based on the 2017 National Electrical Code (NEC®) and is a comprehensive guide to electrical overcurrent protection and electrical design considerations.
To harmonize with modern technical literature and international nomenclature, the term “Surge Protective Device” or “SPD” has been adopted to refer to the same product.
When Siemens first developed the Transient Protection System (TPS) family of surge protectors, we knew early on that hard-wired surge protectors needed fully coordinated safety controls.
SPD has hired 185 male and 21 female recruits during its recent hiring surge (Jan 2025-Mar 2026), resulting in a 10% hiring rate of female candidates. The number of male and female test eligible applicants doubled between 2023 and 2024 and has been holding steady through May 2026.
We want to see you through every phase of your safety optimization projects while ensuring you exceed the standards set for your unique industry.
Locating SPD installation points is a relatively easy step in developing a surge protection plan. Selecting and sizing surge protective devices is not as simple, but Siemens has solutions for virtually all applications.
