ABB Thermal Overload Relay, 3 Poles, 4.2 to 5.7A Current Setting Range - TF42 Series - 1SAZ721201R1038 TF42-5.7

Make sure your motor enjoys a long life with this thermal overload relay from ABB. It has clips and three terminal prongs, so you can plug it directly into your AF series contactor (764-8983). Bimetal elements and a trip class of 10 ensure it quickly cuts off power when an overload or phase failure is detected. A trip indicator on the front gives you clear local signalling. The unit features a dial for adjusting the current setting between 4.2 and 5.7A to match your motor's rating, ensuring reliable overload protection. Thanks to ambient air compensation, this relay handles fluctuating temperatures between -25°C and +60°C with no problem.
