ABB PR112P Air Circuit Breaker For Low Voltage Power Distribution In Industrial And Commercial Facilities

Meet the ABB PR112P Air Circuit Breaker—a rugged, reliable safeguard for low voltage power distribution in industrial and commercial facilities. Built to endure demanding environments, the PR112P delivers precise overcurrent protection with adjustable trip settings and robust interruption capability, helping you keep critical operations online and minimize downtime during faults.

Designed for what matters

The PR112P is ideal for main incoming feeders and switchboards where flexible protection architecture and dependable isolation of faults are essential. Its adjustable trip settings enable you to tailor protection curves to your network, balancing safety with uptime, while its high interruption capacity lets it clear severe fault currents without collateral damage to upstream equipment.

Key benefits at a glance

• Adjustable trip settings for precise coordination with downstream devices and system protection curves.
• High interruption capacity to rapidly interrupt fault currents and protect feeders, switchgear, and connected loads.
• Durable, industrial-grade design engineered for reliability in harsh environments common to industrial and commercial facilities.
• Versatile application suitable for main incoming feeders and switchboards across low-voltage power distribution networks.
• Compact integration compatible with existing panels and layouts, simplifying installation and future upgrades.

Ideal use cases

Whether you're outfitting a new facility or upgrading an aging distribution network, the PR112P excels in:

• Protecting main incoming feeders at the point of entry to your building’s electrical system.
• Providing reliable fault isolation in central switchboards that serve multiple production lines or zones.
• Establishing strong protection for critical loads where uptime is essential, such as data centers, manufacturing floors, and large commercial complexes.

What sets the PR112P apart
