1SAZ421301R1006 ABB TA200DU-200-V1000 Thermal Overload Relay 150 … 200 A

Why Choose the ABB 1SAZ421301R1006 TA200DU-200-V1000 Thermal Overload Relay?

The ABB 1SAZ421301R1006 (TA200DU-200-V1000) is a robust thermal overload relay designed to provide reliable electromechanical protection for high-current three-phase motors in industrial control and automation systems. As part of the proven ABB TA200DU thermal overload relay series, it protects motors against damaging overload and phase failure conditions.

The TA200DU-200-V1000 features a wide 150–200 A adjustable current setting range and trip class 10A, allowing the protection level to be matched to the rated current of the connected motor. Integrated temperature compensation helps maintain dependable tripping characteristics across changing ambient conditions, while the trip-free mechanism ensures protection cannot be defeated by holding the reset control.

This V1000 version is the ATEX variant of the TA200DU-200 and is designed for applications requiring appropriate overload protection in potentially explosive environments. The relay provides a normally closed trip contact and normally open signal contact, selectable automatic or manual reset, STOP and TEST functions, and clear trip indication for effective motor protection and fault management.

Key Advantages

• Reliable thermal overload and phase failure protection for industrial motors.
• Wide 150–200 A adjustable current range for high-current motor applications.

Reliable Thermal Protection for Industrial Motors

Thermal overload relays such as the ABB TA200DU-200-V1000 monitor the current flowing to a motor and respond when sustained overload conditions create a risk of excessive heating. By interrupting the contactor control circuit when an overload or phase failure occurs, the relay helps protect motor windings and other components against thermal damage and premature failure.

The TA200DU-200-V1000 combines an adjustable 150–200 A setting range with trip class 10A characteristics, temperature compensation and a trip-free mechanism. Its integrated auxiliary contacts, automatic or manual reset selection and STOP and TEST functions provide the control and diagnostic functionality required for dependable industrial motor starter installations.

Typical Applications

• High-current industrial motor starters.
• Motor control centres and switchgear assemblies.
• Industrial pumps, fans and compressors.
• Conveyor and material handling equipment.
• Manufacturing and process machinery.
• ATEX motor protection applications in potentially explosive environments.
