APC by Schneider Electric G35TSBPAR20K30F Galaxy 3500 Parallel Maintenance Bypass Cabinet
Overview
The G35TSBPAR20K30F is a freestanding parallel maintenance bypass cabinet for the APC by Schneider Electric MGE Galaxy 3500 UPS series. It lets you route load power around up to three paralleled UPS units — each rated 20–30 kVA at 208V, 3-phase — for scheduled maintenance or emergency service without dropping critical loads. At 90,000 VA aggregate bypass capacity, this is the right cabinet for data center and industrial facilities that cannot tolerate a maintenance window that involves a hard transfer. The floorstanding form factor keeps the bypass path physically separate from the UPS chassis and avoids the configuration mistakes that come with integrated bypass switches on multi-module parallel systems.
Compatibility
Designed specifically for the MGE Galaxy 3500 UPS platform in parallel configurations of two or three modules, each in the 20–30 kVA range at 208V. Input is 208V, 60 Hz, three-phase — confirm your facility feed matches before specifying. This cabinet is not rated for single-module deployments or Galaxy 3500 units outside the 20–30 kVA band; APC offers separate bypass products for the 10–20 kVA and 40+ kVA Galaxy 3500 configurations. Certifications include CSA C22.2 No. 107.1 and UL 1778, making it suitable for installations requiring North American safety compliance across data center, healthcare, and industrial environments. For upstream power distribution or complementary network infrastructure planning, verify that switchgear upstream is rated for the full 90 kVA bypass load.
