Technical overview

Built for the demands of modern power systems

Designed for dependable low-voltage distribution, 1000 amp switchgear supports commercial buildings, industrial facilities, and expanding electrical infrastructure. Each system combines UL-listed assemblies with Siemens components, offering flexible configurations, reliable electrical protection, and consistent performance across a range of applications.

Supporting 1000 amp electrical services, these switchgear configurations accommodate three-phase, four-wire systems operating at common low-voltage ratings. Applications may specify 120/240V, 208Y/120V, or 480Y/277V depending on facility requirements. Short-circuit protection is engineered around the available fault current and project-specific electrical specifications.

Assemblies are UL listed and EUSERC compliant, meeting UBC, CBC, and IBC seismic requirements for all zones. Switchgear is available in NEMA 1 (indoor) and NEMA 3R (outdoor) enclosures, providing flexibility for a wide range of installation environments. Each system is built using genuine Siemens components for long-term reliability.

American based manufacturing keeps lead times fast

A project-built 1000A lineup passes through enclosure fabrication, copper bus processing, component installation, and final inspection at our U.S. facility. DEI Power’s Siemens Approved OEM status supports equipment configurations using Siemens components, with drawings reviewed before production.

Standard configurations typically ship in 4–6 weeks.

Project schedules depend on when electrical equipment arrives, not just when drawings are approved. Standard 1000 amp switchgear configurations typically take 4–6 weeks; custom builds generally require 6–12 weeks, subject to project scope, approvals, and component availability at the time of order.
