In the demanding landscape of data centers, industrial facilities, and large-scale IT environments, where power reliability directly impacts operational continuity, a dependable three-phase UPS is non-negotiable. The APC Smart-UPS VT 30kVA 400V (SUVTP30KH4B4S), crafted by Schneider Electric’s APC division, emerges as a scalable, double-conversion online UPS delivering 30kVA (24kW) of robust protection. Tailored for three-phase 400V setups, it excels in safeguarding sensitive loads from disruptions, with features like parallel redundancy and extended battery options.
Why the Smart-UPS VT 30kVA Shines in High-Demand Scenarios
The SUVTP30KH4B4S distinguishes itself through its modular, tower-style design that blends enterprise-level power with the user-friendly ethos of APC’s Smart-UPS line. Its double-conversion topology provides zero-transfer-time switching to battery, delivering clean sine wave output with under 5% distortion—even under full load—while isolating equipment from grid anomalies like surges or frequency shifts. Dual-mains input and internal maintenance bypass further enhance resilience, allowing seamless servicing without downtime.
Professionals in mission-critical sectors praise its scalability: up to four units can parallel for N+1 redundancy or capacity boosts, making it a flexible backbone for growing infrastructures. Real-world testing underscores its stability, with precise voltage regulation (±1%) and quiet 55 dB operation suitable for office-adjacent data rooms.

Compatibility and Streamlined Deployment
Optimized for global three-phase environments, the SUVTP30KH4B4S integrates seamlessly with APC’s XR battery enclosures for runtime extensions up to hours. It’s VFI-SS-111 compliant, supporting diverse loads from servers and storage to medical and industrial controls. Parallel configurations enable redundancy, while the pre-installed network card facilitates remote oversight via SNMP or web interfaces.
Setup is efficient: Certified technicians handle the included 5×8 start-up service, wiring the 3PH + N + G inputs and configuring via the intuitive LCD. Hot-swappable batteries minimize interruptions, and EPO support ensures safety compliance.
The Benefits: Reliability, Scalability, and Eco-Efficiency
Beyond core protection, the SUVTP30KH4B4S delivers strategic value for uptime-focused operations:
- Unmatched Uptime Assurance: Double-conversion ensures <10ms transfer, with overload tolerance up to 150% for 1 minute. Parallel and dual-input features fortify against failures, ideal for data centers or retail backends.
- Flexible Expansion: Add battery modules for tailored runtime or parallel units for 120kVA total capacity, adapting to evolving needs without full overhauls.
- Advanced Oversight: The AP9619 card provides real-time diagnostics, environmental monitoring, and alerts, slashing mean-time-to-repair. Efficiency peaks at 96.4%, curbing energy costs and heat output.
- Sustainable Engineering: RoHS-compliant with recyclable VRLA batteries, it aligns with green initiatives via Schneider’s take-back program—reducing e-waste footprint.
Reviewers highlight its “reliable power protection” and “quiet operation,” though note the hefty footprint as a trade-off for such capacity.
Warranty, Support, and Field Insights
A 1-year repair-or-replace warranty covers the unit, with extendable plans and modular battery services for longevity. Schneider’s ecosystem includes firmware updates and proactive maintenance, sustaining viability post-discontinuation.
User sentiment leans positive: Forums and reviews commend its performance in outage-prone regions, with one 2025 assessment calling it “exceptional for uptime-sensitive ops” despite size challenges. Refurbished availability keeps it economical, but for new installs, the Galaxy VS offers modern enhancements.
Final Thoughts: A Timeless Choice for Resilient Power
The APC Smart-UPS VT 30kVA 400V (SUVTP30KH4B4S) embodies enduring reliability in a compact-yet-powerful package, perfect for three-phase critical loads demanding scalability and precision. Even as a legacy model, its efficiency and modularity make it a smart pick for upgrades or budget builds.
