Product Overview:
The Cutler-Hammer 1155K Starter Heater Element is a critical component designed to provide reliable and precise thermal overload protection for industrial electric motors. Manufactured by Eaton, a trusted leader in power management, this genuine 1155K heater element is engineered to seamlessly integrate with compatible Cutler-Hammer motor starters and overload relays. Its primary function is to sense excessive current draw, which can lead to motor overheating and damage, and initiate a trip mechanism in the overload relay, effectively disconnecting the motor from the power supply. This proactive protection prevents costly motor burnout, reduces unscheduled downtime, and extends the operational lifespan of valuable industrial machinery. Ideal for a wide range of demanding applications, the 1155K ensures the safety and efficiency of your motor control systems.
