ABB TA200DU-175 1SAZ421201R1005 Thermal Overload Relay 130-175A

The ABB TA200DU-175 (article 1SAZ421201R1005) is a thermal overload relay covering a current setting range of 130 to 175 A, designed to protect motors in the main circuit against overload and phase failure. It operates at trip class 10A and connects directly to block contactors. The device is an economical electromechanical protection solution suited to a wide range of motor applications.

Technical specifications:

• Series: TA200DU-175
• ABB article number: 1SAZ421201R1005
• EAN: 4013614286056
• Type: Thermal overload relay
• Current setting range: 130 - 175 A
• Trip class: 10A
• Trip contact: NC
• Signal contact: NO
• Reset: Automatic or manual (selectable)
• Mounting: Direct connection to block contactors; single mounting kits available as accessory

Features and benefits:

• Trip class 10A provides defined overload response timing suited to standard motor starting conditions
• Temperature compensation maintains accurate tripping performance across varying ambient temperatures
• Selectable automatic or manual reset gives flexibility for different installation and maintenance requirements
• Trip-free mechanism ensures the relay cannot be held in the closed position during a trip event
• STOP and Test function allows routine functional checks without disconnecting the relay from the circuit

Applications:

• Overload and phase failure protection for three-phase motors in industrial installations
• Main circuit protection in motor control centers and distribution panels
• Motor starter assemblies using ABB block contactors
• Protection of pumps, fans, compressors, and similar motor-driven equipment in the 130-175 A range
