Air Circuit Breakers (ACB)

Air Circuit Breakers (ACBs) are heavy-duty protective devices used in low-voltage power distribution systems where high current ratings and advanced protection are required. They are commonly installed as main incomers or feeder breakers in switchboards, switchgear, and power distribution panels.

AmpState’s ACB collection includes breakers suitable for commercial, industrial, and infrastructure applications, supporting both new installations and retrofit or replacement requirements.

KEY FEATURES & SPECIFICATIONS (optional but recommended)

ACBs in this collection may include:

• High amperage ratings for main and feeder circuits

• Low-voltage system compatibility

• Electronic trip units with adjustable protection settings

• Draw-out and fixed mounting options

• Compatibility with accessories such as shunt trips, closing coils, auxiliary contacts, and communication modules

Specifications vary by model and manufacturer.

INDUSTRIES & APPLICATIONS

Air circuit breakers are widely used in:

• Industrial power distribution systems

• Commercial buildings and data centers

• Utility substations and infrastructure projects

• Switchboards and low-voltage switchgear assemblies
