CA4-01 ABB Thermal overload relay Provide reliable motor protection
ABB CA4-01 is a thermal overload relay in the ABB CA4 series specifically designed for extremely small power three-phase asynchronous motors, with a rated working current range of 0.1A to 1.6A. This product integrates one normally open (NO) auxiliary contact and features dual protection functions of overload and phase loss. It is suitable for control application scenarios with high requirements for space compactness and protection accuracy. The CA4-01 can be directly assembled with ABB A series contactors to form an integrated motor starting protection unit, which is widely used in automation equipment, building systems and OEM complete sets of equipment.
