ABB TA25DU1.0 Thermal overload relay for contactors A/AE/AL9 - A/AE/AL4, type TA, Class 10, 0.63 - 1.0 A setting range

Applications

TA thermal overload relays are used with A Line contactors for the protection of motors having a nominal voltage of up to 600V AC max per L/CSA (690V AC and 800V DC per IEC).

Features

• Free tripping: the resetting button, even if held in, does not prevent tripping of the thermal overload relay in the event of a fault.
• Temperature compensation
• Phase failure protection according to IEC 947-4-1: Within the limits of the setting range, a reduced tripping time, and thus improved motor protection, is obrtained in case of a phase failure.
• Tripping class: 10A, for TA relays
