ABB TF42-13 1SAZ721201R1045 Thermal Overload Relay 10-13A

ABB TF42-13 (article 1SAZ721201R1045) is an economical electromechanical thermal overload relay for motor main circuit protection. It provides protection against overload and phase failure events across a current range of 10 - 13 A with trip class 10. The relay mounts directly onto block contactors, making it a compact fit for motor starter assemblies.

Technical specifications:

• Series: TF42-13
• ABB article number: 1SAZ721201R1045
• EAN: 4013614398131
• Type: Thermal overload relay
• Current range: 10 - 13 A
• Trip class: 10
• Trip contact: NC
• Signal contact: NO
• Mounting: Direct connection to block contactors
• Accessory: Single mounting kits available separately

Features and benefits:

• Temperature compensation maintains consistent tripping behavior across varying ambient conditions
• Selectable automatic or manual reset gives flexibility in fault-recovery handling
• Trip-free mechanism prevents the relay from being held closed during an active fault
• Integrated STOP function and trip indication simplify fault diagnosis and controlled shutdown
• Phase failure detection guards motor windings against single-phasing damage

Applications:

• Overload and phase failure protection for three-phase motors in industrial machinery
• Motor starter assemblies built around block contactors in control panels
• Pump, fan, and compressor drive protection circuits
• Conveyor and production line motor control installations
