The thermal overload relay 3RU2116-1JB0 from Siemens is used for current-dependent overload protection in the main circuit. Thanks to its wide setting range of 7-10 A, the SIRIUS overload relay 3RU2116-1JB0 provides optimum protection for motors and systems electronic equipment up to 4 kW. One normally closed and one normally open contact are available as auxiliary contacts. Due to its size S00 and a convenient screw connection, the thermal overload relay 3RU2116-1JB0 can be perfectly integrated into the load feeder. Monitoring relays are used in all areas of electrical switchgear technology.
