Westinghouse BF16, Type MW, Thermal Overload Relay Heater Element 966493-F

Description:

The Westinghouse BF16 (Type MW) Thermal Overload Relay Heater Element 966493-F is a replaceable heater element used in thermal overload relay systems to provide motor protection against sustained overcurrent conditions. It functions as part of a motor starter protection assembly, where it heats and trips the overload relay mechanism when motor current exceeds the set threshold for a defined period.

Applications:

The Westinghouse BF16 thermal overload heater element is used in industrial motor control systems, motor starter assemblies, conveyor drives, pumps, compressors, and manufacturing machinery. It is commonly installed in motor control centers (MCCs) and OEM equipment where precise motor overload protection is required to prevent damage from overheating or prolonged electrical overload conditions.
