Introduction to the ABB TA25 Thermal Overload Relay

Protect your motors from dangerous overloads and phase failures with the dependable ABB TA25 thermal overload relay. This essential protective device is engineered for reliability and durability, making it a critical component for engineers, panel builders, and maintenance professionals. Additionally, with its adjustable current range and robust NO/NC auxiliary contacts, this versatile motor protection relay is perfectly suited for a wide range of motor control applications.

Key Features and Benefits of the TA25 Relay

• • Adjustable Current Setting (10-14 A): This thermal overload relay features a precise adjustable setting from 10 to 14 Amps, providing tailored protection for motors with a full load current of up to 14A. Consequently, it ensures optimal performance and prevents motor burnout.
  • Reliable NO/NC Auxiliary Contacts: Equipped with both Normally Open and Normally Closed contacts, this relay offers maximum flexibility for integration into control circuits. Therefore, it can easily trigger alarms, signals, or shutdown sequences in the event of an overload.
  • 3-Pole Protection: The TA25 provides comprehensive 3-pole protection, monitoring all three phases of the motor. This design ensures complete safety against overloads and phase imbalances, which are common causes of motor failure.
  • Low Contact Rating (2.2W): With a contact rating of 2.2W, the auxiliary circuit is designed for low-energy control signals. This makes it ideal for connecting directly to PLC inputs, indicator lights, and other control devices without needing an intermediate relay.
  • Automated Trip Indication: The relay features a clear trip indicator. Specifically, this allows for quick visual diagnostics and faster resetting after a fault condition, minimizing downtime.
  • Trusted ABB Quality: As part of the ABB product family, this overload protector meets the highest industry standards, which guarantees safety, reliability, and a long service life in demanding industrial environments.
