1SAX121001R1102 ABB Control Industrial Automation Components

ABB 1SAX121001R1102 is an Electronic Overload Relay (EOR) designed for direct connection to contactors with screw-clamp connections for outgoing circuits. It features electronic overload protection with an adjustable rated current range of 0.3A to 1A. This ATEX variant includes manual and automatic reset functions, a test trip function, a stop function, and a rotary knob for adjusting the rated motor current. It is equipped with 1NO+1NC auxiliary contacts and operates within a supply voltage range of -25 to +70°C. The device has a net height of 85 mm, a width of 44.4 mm, and a depth of 59.3 mm. It is designed for 3-pole (3P) direct mounting on contactors and offers protection functions against 3-phase overload, phase loss, and electronic overload adjustable for Class 10E / Class 20E / Class 30E. The rated impulse voltage is 6 kV, with a rated insulation voltage of 690 V and a rated operating voltage of 690 V (IEC) and 600 V (UL/CSA). It operates on a DC or 50/60 Hz network frequency, features a visual position indicator for trip indication on the front, and has power dissipation/losses at rated operating conditions per pole ranging from 0.005W to 0.054 W. The operating rate is 15 cycles/hour, with a minimum current of 0.3 A and a maximum current of 1 A.
