CA4-10 ABB Thermal overload relay Provide reliable motor protection
Product Overview
ABB CA4-10 is a compact thermal overload relay in the ABB CA4 series, specifically designed to protect small three-phase asynchronous motors (rated current 0.1-10A) from overload and phase loss faults. This model is equipped with one normally open (NO) auxiliary contact and supports automatic reset function. It can be directly assembled with ABB A series contactors to form an integrated motor starting and protection unit. With high reliability, modular structure and international certification, it is widely used in industrial control cabinets, building automation systems and OEM equipment.
Key features
✅ precise overload protection
Adopting the principle of bimetallic strip thermal sensing, the tripping characteristic complies with the IEC/EN 60947-4-1 standard (Class 10A), ensuring that the power supply of the motor is cut off in time when overloaded.
✅ phase loss protection function
It is equipped with a built-in three-phase current imbalance detection mechanism. Once any phase is disconnected, it will trigger a trip to prevent the motor from burning out due to single-phase operation.
✅ space-saving & flexible installation
The width is only 45mm
Supports 35mm DIN rail mounting
It can be directly assembled on the right side of ABB A series contactors without the need for additional main circuit wiring
✅ security compliance
It has passed global mainstream certifications such as CE, UL, CSA, CCC, and TUV, and complies with RoHS and REACH environmental protection requirements.
✅ easy to maintain
The transparent window allows for a direct view of the tripping status. The reset button is easy to operate and supports upgrading to manual reset (optional accessories are required).
