The BuzzAlert module is used in conjunction with Fuse Saver_® thermal breaker handles to provide an audible alert when the connected circuit trips the selected breaker handle’s amperage limit. This provides technicians with confirmation that the circuit has been shorted, and is especially helpful in noisy shop environments. Comes standard with #8016 Fuser Saver_® Master Kit. Add-on for #8005 Fuser Saver_® Standard Kit.
