Abb CR123C196A Overload Heater Element

Product Description

The ABB CR123C196A is a thermal overload heater element designed for use with bimetallic overload relays in motor protection and control applications. Heater elements work by converting excess current into heat, which causes the bimetallic strip in the relay to deflect and trip the circuit before motor windings sustain damage. This part is installed by licensed electricians and industrial maintenance technicians as part of motor starter assemblies in commercial and industrial electrical systems.

Thermal overload heater elements are sized to match the full-load amperage of the motor being protected. The CR123C196A is suited for motor control center (MCC) applications, standalone motor starter panels, and control enclosures where overcurrent protection is required. It is used in both new installations and replacement service on existing motor control equipment.

Key Features

• Thermal heater element designed for bimetallic overload relay assemblies
• Provides motor overcurrent protection by calibrated heat deflection of the relay bimetallic strip
• Compact form factor suitable for installation in motor starters and MCC buckets
• Replacement-grade component for maintaining motor protection integrity

Compatibility

Designed as an OEM-style replacement heater element for use in compatible ABB thermal overload relay assemblies. Verify relay model and full-load amperage requirements before installation to confirm fitment.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements. De-energize and lockout/tagout the motor starter or MCC bucket completely before removing or installing heater elements. Confirm the heater element rating matches the motor nameplate full-load amps and the overload relay manufacturer sizing chart. Do not energize the circuit until the enclosure is fully reassembled and all connections are secure.
