Description
Ensure uninterrupted power protection with the Vertiv Liebert NMBHW41 Maintenance Bypass Cabinet, designed for the Nfinity UPS system. This robust solution enables full “wrap-around” bypass functionality, allowing your UPS to be serviced or replaced without disrupting power to connected loads. Equipped with a manual bypass transfer switch, input disconnect switch, and branch-rated output circuit breaker, the NMBHW41 is ideal for critical power infrastructure.
The cabinet features LED indicator lamps that provide clear visual confirmation of input, output, and bypass source availability. Available in 16kVA and 20kVA models, the NMBHW41 offers flexibility with circuit protection options: a 100A breaker for the 16kVA model and 125A for the 20kVA model. Backed by a 2-year Vertiv warranty, this bypass cabinet delivers high reliability and operational ease for your power continuity strategy.
