Overview

The WEG ATDR30 (SKU: WATDR30) is a Class CC time-delay fuse rated at 30A for 600VAC or 300VDC applications. Designed for branch circuit protection and small motor circuits, this fuse features time-delay characteristics to handle motor inrush currents without nuisance tripping. Its current-limiting design reduces peak let-through current, protecting sensitive downstream components from damage. The ATDR30 is constructed with a fiberglass body for dimensional stability and a high-grade silica filler for rapid arc quenching. The rejection-style design ensures compatibility only with recommended fuse blocks, preventing improper replacements and enhancing safety. Certified to UL 248-4 and CSA C22.2 No. 248.4, this fuse meets rigorous standards for industrial reliability. Ideal for small motors, contactors, lighting, heating, and other branch circuit applications, the ATDR30 provides dependable overcurrent protection in harsh environments. Its compact Class CC form factor allows for space-efficient installations in control panels and distribution boards.
