Air Circuit Breaker · 2000A, 2500A Frame, 3-Pole, Drawout, Vertical Connection, 85kA @ 480VAC · UL 1066 / CSA Approved · Noark Electric A25R3DV2000
What this product is for
This air circuit breaker is used as a main or feeder breaker in low-voltage power distribution systems where high current capacity, drawout serviceability, and high interrupting performance are required. It is suited to switchgear, OEM assemblies, standby power systems, data centres, healthcare facilities, industrial plants, and large commercial electrical rooms.
Use for
Use for 480VAC distribution systems requiring a 2000A breaker on a 2500A frame, 3-pole protection, drawout mounting, and rear vertical connection. It is commonly selected where maintenance access, breaker isolation, and replacement speed matter in service entrances, main-tie-main lineups, and large feeder sections.
Avoid for
Avoid for small panelboards, branch circuit applications, or installations that require a fixed-mounted breaker, horizontal rear connection, or a different pole count. Confirm switchgear fit, connection orientation, trip unit requirements, and coordination settings before ordering.
Best for
Best for contractors, switchgear builders, and maintenance teams needing a 2000A drawout ACB with 85kA interrupting capacity at 480VAC in a compact 2500A frame platform. Drawout construction helps reduce downtime during inspection, testing, and replacement.
Installed in
Typically installed in low-voltage switchgear, power distribution assemblies, generator distribution sections, and large commercial or industrial service equipment. This product is generally applied in indoor electrical rooms and engineered distribution systems.
Why this product exists
This breaker provides high-current protection and isolation for larger distribution systems where moulded case breakers may not offer the same serviceability, accessory options, or drawout maintenance advantages. In trade use, drawout ACBs are commonly chosen where uptime, selective coordination, and easier servicing are important. Actual performance depends on system design, available fault current, trip settings, and local electrical code.
Compared with similar products
Compared with a fixed air circuit breaker, this drawout version is easier to rack out for maintenance or replacement. Compared with lower interrupting models, this unit is intended for systems with higher available fault current at 480VAC. Compared with smaller frame breakers, the 2500A frame platform supports higher current applications while this specific unit is rated 2000A.
