Air Circuit Breaker · 1600A, 2500A Frame, 3-Pole, Fixed, Vertical Connection, 85kA @ 480V AC · UL 1066 Power Distribution Breaker · Noark Electrical A25R3FV1600
What this product is for
The Noark Electrical A25R3FV1600 is a low-voltage air circuit breaker for commercial and industrial distribution equipment. It is used where a 1600A breaker is required in a 2500A A25 power breaker platform, with fixed mounting, 3-pole switching, rear vertical connection pads, and 85kA interrupting capacity at 480V AC.
Use for
- Main or feeder protection in low-voltage switchgear
- Industrial plants, commercial buildings, OEM assemblies, and large service distribution sections
- Applications requiring a UL 1066 power circuit breaker with fixed installation
- Systems where rear vertical bus or cable landing suits the gear layout
Avoid for
- Branch circuit applications better served by moulded case breakers
- Installations that require drawout construction for maintenance isolation
- Layouts needing horizontal rear connections instead of vertical pads
- Applications requiring a voltage, fault rating, or trip configuration not confirmed for this exact catalogue number
Best for
Best for electricians, switchgear builders, and maintenance teams sourcing a fixed-mounted 1600A air circuit breaker for high-fault commercial or industrial distribution. This format is typically selected when the switchboard is designed around a fixed breaker rather than a drawout cradle.
Installed in
Typically installed in low-voltage switchgear, service entrance equipment, power distribution lineups, generator distribution sections, and large OEM power assemblies. As a rule of thumb, breakers in this class are commonly used where available fault current is too high for lighter-duty protection devices; actual suitability depends on the engineered short-circuit study, coordination, and local electrical code.
Why this product exists
This breaker provides high-current overcurrent protection and switching in larger power distribution systems while fitting the Noark A25 platform. The 2500A frame supports multiple ampacity options in the same family, which can help standardise equipment layouts and replacement planning.
Compared with similar products
Compared with smaller moulded case breakers, an air circuit breaker in this class is typically chosen for larger switchgear, higher service currents, and maintainable power distribution assemblies. Compared with drawout ACB versions, this fixed type is intended for permanently mounted installations and does not provide the same withdrawable maintenance position.
