Shop A25 Series power circuit breakers with 65kA IC ratings at 480V for industrial and commercial applications. These breakers (600A–2500A) offer short-time withstand up to 100kA at 635V, ensuring reliable protection. Available in fixed or drawout mounting, with 3-pole and 4-pole designs for flexible installations.

Replacement air circuit breakers (ACBs) are used in various industrial and commercial applications across Canada. They are primarily employed in:

1. Manufacturing facilities: ACBs monitor machinery and protect against electrical faults in control rooms and operator cabs.
2. Commercial buildings: Office complexes and shopping malls use ACBs to safeguard lighting, HVAC systems, and electronics.
3. Power plants: ACBs protect generators, transformers, and electrical systems, preventing overloads and short circuits.
4. Data centers: ACBs ensure uninterrupted power supply and protect servers and networking equipment2.
   Oil refineries and gas processing plants: ACBs manage power distribution and uphold safety standards in these facilities.
5. Electrical systems in residential and commercial settings: ACBs are used for overload and short-circuit protection.
6. Hydroelectric power stations: For example, BC Hydro is replacing obsolete air-blast generator circuit breakers with modern SF6 technology at the Mica generating station.

Replacement ACBs are particularly important for aging electrical infrastructure, as they offer enhanced safety features and improved performance compared to traditional circuit breakers.
