Overview
The Allen-Bradley 1492-FB3C30 is a 3-pole Class CC fuse holder designed for control circuit and load protection in industrial automation environments. Rated at 30 amperes for voltages from 110 to 600V AC/DC, this compact fuse block provides safe and convenient branch circuit protection for OEM applications, small motor loads, and control circuits. The ventilated housing and finger-safe design reduce installation hazards and panel clutter.
