Description
The Bussmann FRS-R-150 is a Class RK5 time-delay fuse engineered to deliver dependable overcurrent and short-circuit protection in demanding HVAC and industrial electrical systems. With a 150-amp current rating and a 600VAC voltage rating, this fuse is well-suited for motor branch circuit protection, control panels, and power distribution applications where reliable performance is critical.
Class RK5 fuses are recognized for their current-limiting characteristics and time-delay action, allowing motors and other inductive loads to start without nuisance blowing while still providing fast response to dangerous fault conditions. The FRS-R series features a rejection-style ferrule design that prevents the installation of non-current-limiting fuses in Class RK5 fuse holders, adding an important layer of safety to your electrical installation.
