Abb CR123C113B Heater Overload Element

Product Description

The ABB CR123C113B is a thermal heater element designed for use with overload relays in motor control applications. Heater elements respond to current draw by generating heat proportional to load, which in turn actuates the bimetal strip inside the overload relay to trip the circuit when motor current exceeds safe operating limits. Licensed electricians and industrial maintenance technicians install these elements as part of motor starter assemblies in commercial and industrial settings.

Thermal heater elements like the CR123C113B are used in motor control centers, panel-mounted starters, and combination starter units. They are selected based on the full-load amperage rating of the motor being protected. Proper element selection is critical to accurate overload protection and motor longevity. This element is suited for three-phase and single-phase motor starter configurations where thermal overload protection is required.

Key Features

• Thermal heater element designed for current-proportional overload protection
• Compatible with ABB overload relay assemblies in the CR123 series
• Provides bimetal trip actuation based on sustained overcurrent conditions
• Sized for specific motor full-load amperage ranges to ensure accurate trip response

Compatibility

Designed as an OEM-style replacement heater element for ABB thermal overload relays in the CR123 series motor starter lineup.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC guidelines. De-energize and lock out the motor control panel before removing or installing heater elements. Verify that the element amperage rating matches the motor full-load amp rating per the overload relay manufacturer sizing chart before energizing. Do not substitute elements of a different amperage rating as this will compromise overload protection.
