CR123C867A - GE Thermal Unit

The CR123C867A is an overload relay heater element designed for use in CR123 thermal overload relay systems. When your motor is running continuously, even small variations in load can build up heat over time, and this component helps ensure that overheating and overload conditions are detected and managed before equipment damage occurs.

Its function is based on thermal response behavior—adjusting the relay’s trip characteristics as current increases so the motor is protected at the correct threshold. This helps maintain accurate, predictable protection rather than delayed or inconsistent tripping.

Compact and lightweight, the CR123C867A is designed for straightforward replacement within compatible CR123 assemblies, helping reduce downtime and simplify maintenance work.
