High-Voltage Power System Safety Technology - Advanced FCL technologies ensure high-voltage system protection, reducing maintenance costs and improving operational safety.

Transfer switch technology is highly segmented based on end-user application, specifically distinguishing between residential and industrial needs.

Residential Technology: Residential transfer switches are generally low-amperage (typically 100A to 400A) and prioritize simplicity, cost-effectiveness, and ease of installation. Manual Transfer Switches (MTS) and Open Transition ATS are common. The recent technological focus is on smart home integration, allowing homeowners to monitor the switch and generator status via mobile apps. Whole-house switches and load management-equipped switches are popular, enabling smaller, more affordable generators to power large homes by intelligently prioritizing circuits.

Industrial Technology: Industrial switches are high-amperage (up to 4000A or more) and are defined by complexity, high safety ratings, and performance. Key features include microprocessor-based digital controls, Closed Transition operation (CTTS), high short-circuit withstand ratings (WCR), and integration into complex power monitoring and SCADA systems. Industrial technology is highly focused on redundancy, often utilizing dual-fed systems with multiple synchronized generators, and is built for continuous, reliable operation in harsh environments. Technology here is an integral part of an overall power quality and reliability strategy.
