CA5X.2-11 ABB Thermal overload relay Provide reliable motor protection
The ABB CA5X.2-11 is a compact thermal overload relay, specifically designed to protect small three-phase asynchronous motors from overload and phase loss faults. This model is equipped with one normally open (NO) auxiliary contact and is suitable for use in conjunction with ABB AF series contactors to form a complete motor starting and protection unit. With its high reliability, modular design and DIN rail mounting method, it is widely used in industrial control cabinets, building automation systems and OEM equipment.
Typical application scenarios
Industrial automation
It is used for the starting, stopping and protection of medium-voltage motors, such as water pumps, fans, compressors and other equipment.
Power transmission and distribution
Load switching and protection in scenarios such as medium-voltage switch cabinets and substations.
Energy and infrastructure
Auxiliary control of photovoltaic inverters, pumping stations of water treatment plants, and backup power switching systems.
OEM equipment integration
As a standard component embedded in the OEM control cabinet, it enhances the reliability of the entire machine.
