Eaton Freedom Series Thermal Overload Heater Pack Class

Eaton Freedom Series thermal overload heater packs (also called overload heaters, heater coils or heater elements) are the replaceable, current-sensing part of Eaton Freedom thermal overload relays. They protect motors and motor starters from damage caused by sustained overcurrent. Each heater pack is matched to a motor's full load amperage (FLA), so the relay trips when the motor draws too much current.

Key Features:

• Interchangeable design: The heater pack plugs into a compatible Freedom overload relay. You can match protection to the motor by changing the heater pack, without replacing the whole relay.
• Adjustable dial setting: The dial positions let you fine-tune the trip setting around the heater's rated full load current range.
• Bimetallic, ambient-compensated operation: The relay's trip response stays more consistent when ambient temperature changes.
• Class 10 and Class 20 trip options: The product line includes standard trip Class 20 heater packs and Class 10 heater packs, so you can match the trip class to the application.
• NEMA and IEC applications: The Freedom line is designed for NEMA and IEC motor starters and contactors, in a range of sizes.
• Calibrated for service factor motors: The heater packs are calibrated for use with 1.0 and 1.15 service factor motors.

These heater packs are widely used in industrial motor control panels, pumps, fans, compressors, conveyors and other motor-driven equipment. Eaton is a long-established name in electrical and motor control products. Freedom Series heater packs are a dependable, serviceable choice for motor overload protection and for replacing worn or incorrectly sized heaters.
