The thermal overload relay 3RU2126-4CB0 is a size S0 device for motor protection with an adjustable current range of 17 to 22 A and CLASS 10 trip characteristics. It features one normally closed and one normally open auxiliary contact, operates at up to 690 V AC, and has a rated operating current of 22 A. The relay has a power loss of 6.2 W, is mounted via screw terminals, and measures 85 mm in height, 45 mm in width, and 85 mm in depth. It is rated for operation from -40 to +70 °C and complies with IP20 protection on the front and terminals. The device supports manual-automatic reset and is certified for use in hazardous locations under ATEX.
The thermal overload relay 3RU21264CB0 from Siemens is used for current-dependent overload protection in the main circuit. Thanks to its setting range of 17-22 A, the SIRIUS overload relay 3RU21264CB0 provides optimum protection for motors and systems up to 11 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 overload relay 3RU21264CB0 can be perfectly integrated into the load feeder. Monitoring relays are used in all areas of electrical switchgear technology.
