The Siemens SIRIUS 3RU2 thermal overload relay 3RU2126-4AB0 provides motor protection with an adjustable current range of 11 to 16 A and a trip class of 10. It is designed for size S0 mounting, with dimensions of 85 mm height, 45 mm width, and 85 mm depth. The device supports screw terminals for both main and auxiliary circuits, features one normally closed and one normally open auxiliary contact, and operates at up to 690 V AC with a rated operating current of 16 A. It is certified for use in hazardous locations under ATEX and meets IP20 protection for the front and terminals. The relay operates in ambient temperatures from -40 °C to +70 °C and is suitable for installations up to 2,000 m altitude. Power loss is 6.1 W typical.
Thermal overload relay 3RU2126-4AB0 from Siemens is used for current-dependent overload protection in main circuits. Thanks to its setting range of 11-16 A, the SIRIUS overload relay 3RU2126-4AB0 provides optimum protection for motors and systems up to 7.5 kW. One normally closed and one normally open contact are available as auxiliary contacts. Due to its size S0 and a convenient screw connection, the thermal overload relay 3RU2126-4AB0 can be perfectly integrated into a load feeder. Monitoring relays are used in all areas of electrical switchgear technology.
