APC by Schneider Electric WSTS400A600-SPL2 Static Transfer Switch Set

Overview

The APC by Schneider Electric WSTS400A600-SPL2 is a spare part set for a Static Transfer Switch (STS) designed to provide seamless power continuity for critical loads. It supports input voltages from 208V to 600V 3-phase and offers hardwired output connections for single-zone 4-wire (3PH+G) or 5-wire (3PH+N+G) configurations. This unit is intended for deployment in environments demanding high power reliability, such as data centers or industrial automation facilities, where an STS is crucial for preventing downtime during utility or primary power source failures. The model number WSTS400A600-SPL2 signifies its role as a specific component within a larger power protection system.

Compatibility

This spare part set is designed to integrate with APC by Schneider Electric STS systems supporting 400A max line current. It is compatible with systems accepting 208V, 480V, and 600V 3-phase input and output voltages, operating on a 50/60 Hz input frequency. The output connectors are specifically hardwired for single-zone applications, supporting both 4-wire and 5-wire configurations.

Installation Notes

Installation requires hardwiring for both input and output connections. The unit is designed for front mounting and is not rack-mountable. Operating altitude is limited to 3333 ft (1016 m) to ensure optimal performance. Storage conditions allow for a wide temperature range of -40 to 158 °F (-40 to 70 °C) and relative humidity from 5% to 90% non-condensing.
