Air Circuit Breaker · 1200A, 3-Pole, 85kA @ 480VAC · Fixed Mount, Horizontal Connection · Noark Electrical A25R3FH1200
What this product is for
This air circuit breaker is used for main or feeder protection in low-voltage power distribution systems where high available fault current and serviceable breaker construction are required. It suits switchgear lineups, OEM power assemblies, industrial facilities, healthcare buildings and larger commercial installations.
Use for
Use for 480VAC class distribution systems requiring a 1200A, 3-pole fixed-mounted air circuit breaker with horizontal rear connection. It is commonly selected where coordination, maintainability and high interrupting capacity are important.
Avoid for
Avoid for small panelboards, branch-circuit applications or installations that require a drawout breaker. Also confirm terminal orientation before ordering, as this model is the horizontal connection version.
Best for
Best for switchgear builders, industrial electricians and maintenance teams needing a serviceable ACB platform for main distribution or large feeder sections. A 1200A breaker is typically used where calculated load and coordination studies call for this continuous current rating; actual suitability depends on system design, available fault current and local electrical code.
Installed in
Typically installed in low-voltage switchgear, power distribution assemblies, generator distribution sections and OEM equipment. This breaker family is used in industrial, healthcare and commercial applications.
Why this product exists
This model provides high-current circuit protection in a maintainable air circuit breaker format rather than a smaller moulded case platform. The A25 family is designed for low-voltage power circuit breaker applications with UL 1066 construction, 100% continuous current rating at maximum current rating, and accessory options across the platform.
Compared with similar products
Compared with lower-current or moulded case breakers, an air circuit breaker is typically chosen for larger mains and feeders where service access, accessory options and coordination matter. Within the Noark A25 family, this A25R model provides 85kA interrupting capacity, while other variants in the family are available with different interrupting ratings, mounting styles and terminal orientations. Always match the breaker type, connection style and interrupting rating to the switchgear design.
