APC 0M-STSU250HX4 Static Transfer Switch, Upsilon STS 250, 4-Pole, 380-415V, IP00

Ensure continuous power to critical loads with the APC by Schneider Electric static transfer switch. The Upsilon STS 250 is engineered to deliver fast, reliable automatic source transfer so UPS-backed systems, security and surveillance networks, and monitoring equipment remain online during utility or generator transitions. Built for three-phase environments, this STS supports 4-pole switching in 380–415V systems and fits into UPS-centric power architectures where deterministic switching and compatibility matter.

As a precision power-management device from a trusted brand, the STSU250HX4 simplifies integration into data centers, physical security installations, and industrial control rooms. Its compact IP00 design supports indoor rack and panel installations while enabling predictable transfer behavior that reduces outage risk and operational complexity. By adding the APC Upsilon STS 250 to your power protection strategy, you improve availability for critical applications—everything from access control and CCTV to network monitoring and IT infrastructure.

Specify the Upsilon STS 250 for projects that demand seamless source transfer and robust UPS coordination. Contact sales or add to your procurement list to upgrade resilience across your security, surveillance, and mission-critical systems.
