ABB 1SAZ421201R1002

The TA200DU-110 thermal overload relay serves as an economic solution for safeguarding electric motors in the main circuit against overload and phase failure. This device features a trip class of 10A and includes several functionalities such as temperature compensation, a normally closed (NC) trip contact, and a normally open (NO) signal contact. The relay supports both automatic and manual reset options and incorporates a trip-free mechanism along with STOP and Test functions. A trip indication is also provided for operational clarity.

Designed for direct connection to block contactors, the relay maintains a rated operational current of 110 A and can handle auxiliary circuit voltages up to 440 V DC and 500 V AC, while the main circuit can support up to 690 V AC and 440 V DC. The unit is compact, with dimensions of 104 mm in width, 151 mm in height, and 126 mm in depth, weighing 0.76 kg.

Additional specifications include a maximum operating altitude of 2000 m and a temperature range for operation between -25 °C to +55 °C. It is compliant with various international standards, including IEC/EN 60947-1, ensuring its viability for diverse industrial applications. The device also features an IP20 degree of protection for the housing and IP00 for main circuit terminals, making it suitable for environments with pollution degree 3.

This overload relay is compatible with several models, including A145, A185, AF145, AF185, AF190, and AF205, and is backed by comprehensive technical...
