ABB UXAB239290939 Circuit Breakers 110V-50Hz and 127V-60Hz

Description

• The ABB UXAB239290939 is a U.V.R. (Under Voltage Release) device designed for use in electrical systems. This particular U.V.R. is versatile and is configured to work within two different voltage ranges: 110V-50Hz and 127V-60Hz, denoting compatibility with both 50Hz and 60Hz electrical systems. The "G-LG-F" in the designation may refer to specific features or configurations that are unique to this model.

• Voltage Release (U.V.R.) devices are commonly used in electrical equipment, including circuit breakers, to ensure that the circuit remains disconnected when the voltage falls below a certain threshold. This is crucial for safety and prevents unintended re-energization during voltage drops or power outages.
