APC by Schneider Electric G35TSBP10K15F vs Vertiv GXT5-15KMVRT11UXLN: Specification Comparison
Both the APC by Schneider Electric G35TSBP10K15F and the Vertiv Liebert GXT5-15KMVRT11UXLN are 15 kVA-class uninterruptible power supply solutions intended for business-critical infrastructure. The APC unit is a maintenance bypass cabinet designed to pair with an existing UPS, while the Vertiv is a standalone online double-conversion UPS with integrated bypass and management capabilities. Buyers evaluating both are typically protecting server rooms or data center edge deployments at the 15 kVA tier, where topology, efficiency, physical footprint, and management interfaces are the primary decision drivers.

What UPS topology and power architecture does each unit deliver?
The APC G35TSBP10K15F is explicitly a maintenance bypass cabinet rated at 15 kVA output, operating on a three-phase input and three-phase output architecture at 208V. It is not a standalone UPS — it requires a paired UPS unit to provide actual power conditioning. Its role is to allow the connected UPS to be serviced without dropping the load. Input frequency is specified as 50/60 Hz. No efficiency rating or topology (e.g., double conversion) is provided in the available specs for this product.
The Vertiv GXT5-15KMVRT11UXLN is a standalone online double-conversion UPS rated at 15,000 VA / 15,000 W (unity power factor). It accepts a typical input of 208 VAC with a range of 176–280 VAC and delivers a user-configurable output of 208/120 VAC. Efficiency is specified at up to 98% in Active ECO Mode and up to 95% in standard online mode. The double-conversion topology means all output power is continuously synthesized, providing zero transfer time to battery and full isolation from input disturbances.
How do the physical form factor and environmental operating envelopes compare?
The APC G35TSBP10K15F is a tower form factor unit with a specified width of 351 mm. Height and depth are not provided in the available specs. It operates from 0–40 °C and stores from 0–45 °C, with operating relative humidity of 0–95% (non-condensing not specified) and storage relative humidity of 0–95%. Operating altitude is 0–3,000 m and non-operating altitude extends to 9,000 m. Product color is black.
The Vertiv GXT5-15KMVRT11UXLN offers a flexible rack/tower form factor. Physical dimensions are fully specified: 19.0 in H × 16.9 in W × 26.7 in D, with a weight of 396.6 lbs. Operating temperature matches the APC at 0–40 °C (+32 to +104 °F). Humidity, altitude, and storage temperature specs are not provided in the available data. The Vertiv's hardwired input/output wiring and 11U rack footprint make it suited to structured rack deployments, while its gravity-sensing LCD panel adapts orientation for both rack and tower installation.
What management interfaces, certifications, and integration options does each product offer?
The APC G35TSBP10K15F provides an LCD display, LED indicators, and an audible alarm. No network management interfaces, communication protocols, or software integration options are listed in the available specifications. Certifications include CSA, CSA C22.2 No. 107.1, and UL 1778.
The Vertiv GXT5-15KMVRT11UXLN ships with a factory pre-installed Vertiv Liebert IntelliSlot RDU120 SNMP/Web card, enabling SNMP and web-based management out of the box. Additional interfaces include USB, RS485, RS232, a terminal block, and an external battery connector. Out-of-band management is available via serial connection. The full-color graphic LCD panel with gravity-sensing orientation provides on-device status and configuration. Certifications include ENERGY STAR 2.0, UL1778, c-UL, RoHS2, and REACH — a broader compliance portfolio than the APC unit. Hot-swap battery capability is not specified for the Vertiv in the available data, whereas the APC lists hot-swap battery as yes.
Which should you choose: the G35TSBP10K15F or the GXT5-15KMVRT11UXLN?
Our take: The GXT5-15KMVRT11UXLN is the stronger choice when a buyer needs a complete, standalone power protection solution with full management visibility, while the G35TSBP10K15F is appropriate only as a service-continuity accessory for an existing UPS installation. Three concrete spec deltas underscore this: the Vertiv delivers a specified efficiency of up to 98% in ECO Mode versus no efficiency figure provided for the APC; the Vertiv ships with factory-installed SNMP/web management and five interface types versus the APC's LCD-and-alarm-only panel; and the Vertiv carries ENERGY STAR 2.0, UL1778, c-UL, RoHS2, and REACH certifications versus the APC's CSA and UL 1778. Buyers building a net-new 15 kVA protected circuit should select the Vertiv as the primary UPS. Buyers who already own a compatible APC MGE Galaxy 3500 UPS and need to add maintenance bypass capability without dropping the load should evaluate the G35TSBP10K15F for that specific ancillary role.

Frequently Asked Questions
Which should you choose: the G35TSBP10K15F or the GXT5-15KMVRT11UXLN?
The GXT5-15KMVRT11UXLN is the stronger choice when a buyer needs a complete, standalone power protection solution with full management visibility, while the G35TSBP10K15F is appropriate only as a service-continuity accessory for an existing UPS installation. Three concrete spec deltas underscore this: the Vertiv delivers a specified efficiency of up to 98% in ECO Mode versus no efficiency figure provided for the APC; the Vertiv ships with factory-installed SNMP/web management and five interface types versus the APC's LCD-and-alarm-only panel; and the Vertiv carries ENERGY STAR 2.0, UL1778, c-UL, RoHS2, and REACH certifications versus the APC's CSA and UL 1778. Buyers building a net-new 15 kVA protected circuit should select the Vertiv as the primary UPS. Buyers who already own a compatible APC MGE Galaxy 3500 UPS and need to add maintenance bypass capability without dropping the load should evaluate the G35TSBP10K15F for that specific ancillary role.
Can the G35TSBP10K15F work as a standalone UPS replacement for the GXT5-15KMVRT11UXLN?
No. The G35TSBP10K15F is a maintenance bypass cabinet, not a standalone UPS. It requires a paired UPS unit to condition and protect power; it does not itself provide battery backup or power conversion. The GXT5-15KMVRT11UXLN is a complete online double-conversion UPS and is the appropriate choice for standalone power protection at 15 kVA.
Which unit offers better remote monitoring and management for an IT team?
The Vertiv GXT5-15KMVRT11UXLN provides significantly richer management options. It ships with a factory pre-installed IntelliSlot RDU120 SNMP/Web card and supports USB, RS485, RS232, and serial interfaces with SNMP and web protocols enabled out of the box. The APC G35TSBP10K15F lists only an LCD display, LED indicators, and audible alarm — no network management interfaces are specified in the available data.
Which product has a broader compliance and certification footprint for regulated environments?
The Vertiv GXT5-15KMVRT11UXLN lists ENERGY STAR 2.0, UL1778, c-UL, RoHS2, and REACH certifications. The APC G35TSBP10K15F lists CSA, CSA C22.2 No. 107.1, and UL 1778. For deployments requiring ENERGY STAR, RoHS2, or REACH compliance — common in government, healthcare, or EU-bound equipment — the Vertiv's certification set is more comprehensive based on the available specifications.
