ABB TA200DU-150 1SAZ421201R1004 Thermal Overload Relay

ABB TA200DU-150 (article 1SAZ421201R1004) is a thermal overload relay with a current setting range of 110 - 150 A. It serves as an electromechanical protection device for the main circuit, shielding motors from overload conditions and phase failure. The relay carries trip class 10A, enabling fast response to abnormal current levels before damage occurs.

Technical specifications:

• Series: TA200DU-150
• ABB article number: 1SAZ421201R1004
• EAN: 4013614286049
• Type: Thermal overload relay
• Current setting range: 110 - 150 A
• Trip class: 10A
• Trip contact: NC (normally closed)
• Signal contact: NO (normally open)
• Reset mode: Automatic or manual, selectable
• Mounting: Direct connection to block contactors; single mounting kits available as accessory

Features and benefits:

• Trip class 10A provides fast tripping response to protect motors from prolonged overload currents
• Phase failure detection guards against motor damage caused by a missing or unbalanced supply phase
• Temperature compensation keeps trip characteristics consistent regardless of changes in ambient temperature
• Trip-free mechanism prevents the relay from being held in the closed position during a fault
• Selectable automatic or manual reset allows the system recovery mode to be matched to the application requirements

Applications:

• Overload protection of large three-phase motors in industrial drive systems
• Motor protection in heavy-duty pump and fan installations
• Use within motor control centres alongside ABB block contactors
• Protection of high-current motors in process and manufacturing plant
