LayerZero Power Systems Expands Product Line with 2000 A, Four-Pole Static Transfer Switch

By Brian Love

LayerZero Power Systems, a leading innovator in power quality and distribution solutions since 2001, has expanded its Series 70E Static Transfer Switch (eSTS) product line with a new 2000 A, Four-Pole configuration, designed to deliver unparalleled safety, performance, and reliability in mission-critical environments, such as data centers.

Building on the proven reliability of LayerZero’s three-pole eSTS designs, the 2000 A four-pole design introduces true break-before-make neutral switching, ensuring safe and seamless transfers between power sources, even under unbalanced load conditions. This capability makes the switch particularly well-suited for operations where uptime and power integrity are essential.

Key Features of the 2000 A Four-Pole eSTS include:

• True Four-Pole Switching: Controls all conductors (phases A, B, C, and neutral) for complete isolation during transfers. Neutral switching enhances grounding, voltage stability, and safety compared to traditional three-pole systems.
• Ultra-Fast Transfers: Transfers between sources in less than a quarter cycle, minimizing disruptions and protecting sensitive IT loads from voltage disturbances.
• Enhanced Operator Safety: By stabilizing and managing unbalanced electrical loads, neutral switching helps minimize the risk of electrical shock, prevent equipment failure, and mitigate voltage malfunctions. The LayerZero® Series 70E eSTS is designed to help operators work safer by design.
• Waveform Capture and ITIC Plotting: The system is capable of capturing every event with time-stamped waveform snapshots, generating ITIC plots. These plots help produce easy-to-read power quality reports and deliver a clear assessment of whether sensitive equipment was affected by an event.
• Integrated Event Logging and Diagnostics: Utilizing our built-in diagnostics, event logging, and waveform capture, the LayerZero® Series 70E eSTS can continuously monitor voltage, current frequency, and power factors, providing operators with visibility into system performance and behavior.

With the introduction of the 2000 A Four-Pole Series 70E eSTS, LayerZero Power Systems reinforces its commitment to innovation in power distribution. Designed for the most demanding of mission-critical environments, the system's design offers a smarter and safer tool for facilities to maintain uninterrupted operations. Compared to a traditional three-pole model, the LayerZero® Series 70E eSTS ensures safety and reliable power quality, making it a future-ready choice.
