Eaton Thermal Overload Heater Element

Eaton thermal overload heater elements, also called overload relay heaters or thermal units, give motor starters and contactors dependable overload protection. Each element is installed in a compatible Eaton overload relay. When motor current stays above its rated level, the element heats up and trips the relay. This disconnects the motor before overheating damages the windings.

Key Features:

• Thermal overload protection for motor starters and motor control circuits
• Matched to motor full-load current so the trip point is right for the application
• Works with compatible Eaton overload relays and starters
• Helps prevent motor burnout, downtime, and costly repairs
• Built for industrial and commercial motor control use
• Replaceable, so you can change the protection level without replacing the whole relay

Eaton is a well-known name in electrical power management and motor control. Its heater elements are used in HVAC, pumps, conveyors, fans, compressors, and general industrial machinery. Choose the element that matches your motor's full-load current rating and your overload relay series.
