Eaton FH46 Type a B Overload Heater Element

Product Description

The EATON FH46 is a thermal overload heater element designed for use with Type A and Type B overload relays in motor control applications. Heater elements like the FH46 generate a calibrated amount of heat proportional to motor current, allowing the overload relay to trip and protect the motor from sustained overcurrent conditions. At 0.03 pounds and compact dimensions of 2.1 inches by 1.3 inches by 0.8 inches, this element is a direct-fit replacement component installed by licensed electricians and motor control technicians during panel assembly or field service.

The FH46 is suited for residential and light commercial motor control centers, combination starters, and manual or magnetic starter assemblies where Type A or Type B overload relays are specified. It is commonly installed in heating, ventilation, pump, and compressor motor circuits where reliable thermal overload protection is required. Selecting the correct heater element for the motor full-load amperage rating is critical to proper relay calibration and motor protection.

Key Features

• Designed for use with Type A and Type B EATON overload relays
• Thermal heater element provides calibrated overcurrent protection proportional to motor current draw
• Compact form factor fits standard starter and motor control enclosures
• Lightweight at 0.03 pounds for easy handling during installation
• Direct OEM-style replacement for field or panel service

Compatibility

Designed as an OEM-style replacement heater element compatible with EATON Type A and Type B overload relays used in motor starter and motor control applications.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements and local electrical codes. De-energize and lock out the starter or motor control center before removing or installing heater elements. Verify the heater element selection matches the motor full-load amperage per the manufacturer selection chart. Do not energize the circuit until all elements are fully seated and the enclosure is properly closed.
