Cutler & Hammer Electric Heat Sequencers

Overview

The Cutler Hammer H1027 is an overload relay heater element designed for use in thermal overload relay assemblies. It converts excess current into heat, causing the relay to trip and protect motors and control circuits from damage due to sustained overcurrent conditions. The H1027 is compact, measuring approximately 2.01 inches by 2.01 inches by 0.98 inches and weighing 0.10 pounds. It is installed by licensed electricians and industrial maintenance technicians as part of motor starter and contactor assemblies in commercial and industrial control panels. This heater element is suited for motor protection applications where thermal overload relays are used to guard against overheating caused by overloads, phase loss, or locked-rotor conditions. It fits into the heater element socket of compatible Cutler Hammer thermal overload relays and is a direct replacement for worn or damaged elements in existing assemblies. Typical installations include motor control centers, combination starters, and industrial control panels in commercial or light industrial settings.
