APC by Schneider Electric MGE Galaxy 3500 Maintenance Bypass Cabinet 10-15KVA 208V - G35TSBP10K15F

APC by Schneider Electric G35TSBP10K15F MGE Galaxy 3500 Maintenance Bypass Cabinet

The APC by Schneider Electric G35TSBP10K15F is a dedicated floormount maintenance bypass cabinet designed for the APC MGE Galaxy 3500 three-phase UPS in 10–15 kVA configurations at 208V. The bypass cabinet's core function is straightforward but operationally critical: it lets you isolate and service the UPS without dropping power to your connected load — essential in any environment where unplanned downtime is unacceptable.

Overview

Data centers, server rooms, and critical infrastructure installations running the Galaxy 3500 platform need a path to perform UPS maintenance without cutting power to the load. The G35TSBP10K15F solves this by providing a hardwired manual bypass route that keeps downstream equipment energized while the UPS is taken offline for battery replacement, firmware updates, or internal servicing. The floormount tower form factor pairs directly with the Galaxy 3500 chassis and fits standard raised-floor or hard-floor machine room deployments. The cabinet ships in black and integrates an LCD display alongside LED status indicators so technicians have clear visual confirmation of bypass state during the switchover procedure.

Key Features

• 15 kVA Output Capacity: Rated to handle the full load range of the 10–15 kVA Galaxy 3500, meaning you can execute a bypass transfer without needing to shed any connected equipment first — critical in high-density server or broadcast environments where load shedding triggers cascading shutdowns.
• Three-Phase Input and Output (50/60 Hz): Both input and output are three-phase, matched to the Galaxy 3500's power architecture. This maintains balanced phase loading through the bypass path, which matters for connected three-phase PDUs and server infrastructure sensitive to phase imbalance.
• LCD Display with LED Indicators: The onboard LCD and LED indicators give real-time status confirmation of bypass state, active alarms, and operational mode — no need to rely on a separate management interface during a maintenance event. Technicians see exactly where the switching state is at a glance.
• Audible Alarms: Built-in audible alarms alert personnel to abnormal conditions during the bypass procedure, reducing the risk of an unattended switchover going unnoticed in a noisy machine room environment.
• Hot-Swap Battery Support: The hot-swap battery capability means battery servicing on the Galaxy 3500 can proceed without interrupting the load — the bypass cabinet provides the alternate power path while the UPS battery string is exchanged, cutting planned maintenance windows significantly.
• Operating Range 0–40°C, 0–95% RH: Covers the full operating envelope of a standard data center or industrial electrical room — from a chilled computer room at 18°C to a warmer IDF closet or factory floor at 40°C. The 0–95% non-condensing humidity rating handles coastal and humid-climate installations without derating.
• Altitude Rating up to 3,000m Operating / 9,000m Storage: Usable at high-altitude facilities (mountain data centers, elevated industrial sites) up to 3,000m without derating — a spec that often gets overlooked until a deployment in Denver or Mexico City.
• UL 1778 / CSA / CSA C22.2 No. 107.1 Certifications: These certifications satisfy the electrical safety requirements for North American commercial and industrial installations. UL 1778 specifically covers uninterruptible power supplies and associated equipment — your facilities team and AHJ will expect this listing on any hardwired bypass equipment.
• 351mm Width Floormount Tower: The narrow 351mm footprint keeps the footprint compact alongside the Galaxy 3500 chassis — relevant in tight equipment rooms where floor space is allocated per rack unit of width, not just depth.

Integration & Compatibility

The G35TSBP10K15F is purpose-built for the MGE Galaxy 3500 UPS platform in the 10–15 kVA range at 208V. It is not a universal bypass panel — confirm your Galaxy 3500 model's kVA rating and input voltage before ordering. The three-phase 208V wiring and the bypass cabinet's physical interface are matched to the Galaxy 3500's output terminals; pairing with other Galaxy models or voltage variants (400V European configurations, for example) requires a different SKU. For full power infrastructure planning, verify that your building's upstream three-phase feed, branch circuit breaker sizing, and conduit runs are compatible with the Galaxy 3500 plus bypass cabinet's combined inrush and steady-state draw at 15 kVA.

Frequently Asked Questions

Q: What UPS models is the G35TSBP10K15F compatible with?

A: The G35TSBP10K15F is designed specifically for the APC MGE Galaxy 3500 UPS in 10–15 kVA configurations at 208V. It is not a universal bypass cabinet — verify your Galaxy 3500 model's kVA and voltage rating before ordering.

Q: Can the G35TSBP10K15F be used to service the UPS while the load stays powered?

A: Yes. That is the primary function of this bypass cabinet — it provides a manual bypass path so the Galaxy 3500 UPS can be isolated for maintenance, battery replacement, or servicing without interrupting power to the connected load.

Q: What certifications does the G35TSBP10K15F carry?

A: The G35TSBP10K15F is certified to UL 1778, CSA, and CSA C22.2 No. 107.1 — the relevant North American safety standards for UPS and associated bypass equipment.

Q: What is the operating temperature range for the G35TSBP10K15F?

A: The cabinet operates from 0°C to 40°C and stores from 0°C to 45°C, with operating relative humidity up to 95% (non-condensing). Operating altitude is rated to 3,000m.

Q: Is the G35TSBP10K15F a tower or rack-mount unit?

A: It is a floormount tower unit, 351mm wide, designed to sit alongside the MGE Galaxy 3500 chassis on the data center or electrical room floor.

Q: Does the G35TSBP10K15F support hot-swap battery replacement?

A: Yes. Hot-swap battery capability is supported, allowing battery string replacement on the paired Galaxy 3500 without dropping the load, provided the bypass cabinet is engaged.

Ted Perry

The G35TSBP10K15F does one thing, and it needs to do it without hesitation: hand off the load from the Galaxy 3500 UPS to a direct utility bypass path so the UPS can be serviced without a power interruption. That 15 kVA output capacity ceiling is the number to pin your design around — it's the hard ceiling for the paired Galaxy 3500 in this voltage class, and this cabinet is rated to carry the full load through the bypass path, not just a reduced subset.

Technical Highlights:

• Three-Phase Architecture (50/60 Hz): Both input and output are three-phase, keeping balanced phase loading intact through the bypass path — critical for facilities running three-phase PDUs or UPS-fed server racks that respond poorly to single-phase fallback conditions.
• UL 1778 / CSA C22.2 No. 107.1 Certification: These are the certifications your facilities manager and AHJ inspector will ask for on any hardwired bypass equipment. UL 1778 is specific to UPS systems and associated switchgear — not a general electrical listing.
• Operating Altitude to 3,000m: Frequently overlooked, but relevant if you're installing at elevation. High-altitude sites (above ~1,500m) often see deratings on power equipment; this unit is rated to 3,000m without adjustment.

Deployment Considerations:

• The G35TSBP10K15F is a hardwired permanent installation — factor conduit routing, three-phase 208V branch circuit sizing, and clearance for the floormount tower footprint (351mm wide) into your room layout before the equipment arrives on site.
• This cabinet is matched to the Galaxy 3500 at 208V, 10–15 kVA. It is not cross-compatible with Galaxy 3500 400V international models or other Galaxy UPS families — an easy ordering error if the procurement team is sourcing from a multi-voltage environment.

Best fit: a North American data center or critical infrastructure electrical room running the MGE Galaxy 3500 at 10–15 kVA where facilities policy requires zero-downtime UPS maintenance windows and the AHJ requires UL 1778-listed bypass equipment.
