CAL19-11 ABB Thermal overload relay Thermal overload protection small medium sized motors
ABB CAL19-11 is a highly efficient and reliable thermal overload relay, specifically designed to protect small and medium-sized three-phase asynchronous motors from overload and phase loss faults. This model supports one normally open auxiliary contact, features a compact design and high reliability, and is widely used in industrial automation, building automation and infrastructure projects. It can be used in conjunction with contactors to provide a comprehensive motor protection solution.
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.
