ABB 1SAZ711201R1013

The T16-0.31 thermal overload relay serves as an electromechanical protective device designed for the main circuit, ensuring reliable protection for motors during overload conditions or phase failures. This device features a trip class of 10 and is equipped with temperature compensation mechanisms. Additionally, it incorporates a trip contact (NC), a signal contact (NO), and options for both automatic and manual reset, alongside a trip-free mechanism, STOP function, and trip indication.

With dimensions of 45 mm in width, 76.7 mm in height, and a depth of 53.5 mm, the relay weighs 0.1 kg. It is designed for direct connection to mini contactors or block contactors. The relay accommodates a rated operational voltage of 690 V AC for the main circuit and 600 V AC/DC for the auxiliary circuit, operating within a frequency of 50 Hz and 60 Hz. The device maintains a rated impulse withstand voltage of 6 kV and a rated insulation voltage of 690 V.

In terms of connectivity, the T16-0.31 supports flexible and rigid wire connections across various configurations, with specific tightening torques for auxiliary and main circuits. It operates effectively within an ambient temperature range of -25 °C to +60 °C and can withstand shock and vibrations as per IEC standards.

This thermal overload relay is compliant with multiple standards including IEC/EN 60947-1, UL 60947-1, and others, ensuring its suitability for diverse applications.
