Air Circuit Breaker · 800A, 2500A Frame, 3-Pole, Fixed Vertical Connection, 85kA at 480V · Noark Electrical A25R3FV800
What this product is for
The Noark A25R3FV800 is a low-voltage air circuit breaker for commercial and industrial power distribution systems. It is an 800A, 3-pole, fixed-mounted breaker in the A25 series with rear vertical connection pads and an 85kA interrupting rating at up to 508Vac.
Use for
Use for main or feeder protection in switchboards, switchgear lineups, generator distribution, large OEM equipment, and facility power systems where an 800A ACB is specified. It suits applications that need a fixed breaker rather than a drawout assembly.
Avoid for
Avoid for branch-circuit applications, panelboards that require molded case breakers, or installations that need a drawout breaker for faster maintenance isolation. Also avoid where the specified fault duty, mounting style, or connection orientation does not match the equipment design.
Best for
Best for switchgear builders, industrial facilities, and electrical contractors replacing or specifying a fixed 800A air circuit breaker in a 2500A frame platform. This format is commonly selected when the project requires ACB performance, field serviceability, and coordination in larger distribution assemblies.
Installed in
Typically installed in low-voltage switchgear, power distribution rooms, industrial plants, commercial buildings, infrastructure projects, and OEM-built assemblies. Rear vertical connections are selected where the bus arrangement is designed for vertical pad termination.
Why this product exists
This breaker provides high available fault-current protection in larger distribution systems while fitting within Noark's A25 2500A frame family. For buyers standardizing parts, the 2500A frame platform can simplify family selection across multiple ampere ratings, depending on the switchgear design.
Typical guidance: air circuit breakers in this size range are commonly used as mains or large feeders rather than final branch protection. Actual suitability depends on the equipment rating, coordination study, available fault current, and local electrical code.
Compared with similar products
Compared with a drawout ACB, this fixed version is generally chosen when the assembly does not require a withdrawable cradle. Compared with a molded case breaker, an air circuit breaker is typically selected in larger switchgear where maintainability, accessory options, and system coordination are more important.
