Description
Maintaining older industrial infrastructure is simple with the HFA3025, a 25A, 3-pole molded case circuit breaker. It offers a straightforward solution for facilities relying on classic distribution equipment. This bolt-on MCCB installs securely into Westinghouse Pow-R-Line panelboards and switchboards. As a cross-reference to the newer HFD3025, it provides an exact physical match for legacy enclosures. Delivering 25kAIC at 480V, it relies on fixed thermal-magnetic trip technology.Specifications
