ABB TF42-10 1SAZ721201R1043 Thermal Overload Relay 7.6-10A

The ABB TF42-10 (article 1SAZ721201R1043) is a thermal overload relay providing electromechanical protection for motor main circuits. It defends motors against overload conditions and phase failure, with a current setting range of 7.6 to 10 A and trip class 10.

Technical specifications:

• Series: TF42-10
• ABB article number: 1SAZ721201R1043
• EAN: 4013614398124
• Current setting range: 7.6 - 10 A
• Trip class: 10
• 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:

• Guards motors against damage from overload conditions and phase failure
• Temperature compensation maintains consistent tripping behaviour across varying ambient conditions
• Trip-free mechanism prevents the protective function from being bypassed during a fault
• Selectable automatic or manual reset provides flexibility for system restart procedures
• STOP function and trip indication support swift fault identification and safe shutdown

Applications:

• Motor starter assemblies in industrial control panels
