Allen-Bradley 193-1EFQH Overload Relay for Motor Starters

The Allen-Bradley 193-1EFQH (193-1EFQH) is an overload relay designed for motor branch circuits, contactors, and motor starter installations in industrial control systems. Operating within the Allen-Bradley Bulletin 193 family, this unit provides critical thermal and electrical overload monitoring to protect motors, power distribution equipment, and connected machinery from phase loss, extended overcurrent conditions, and overheating during continuous duty cycles. Built for dependable performance in demanding control panels and switchgear enclosures, the 193-1EFQH integrates directly with compatible motor control assemblies and contactor bases. With a net weight of approximately 10 kg, this heavy-duty component provides robust construction suited for manufacturing facilities, process automation systems, conveyor lines, and heavy-machinery motor control centers. It serves as an essential maintenance and replacement solution to restore designed operating parameters, reduce equipment downtime, and safeguard three-phase electric motors across industrial production environments.
