Product description
Overload relay Siemens SIRIUS 3RU21261HB0
The thermal overload relay 3RU21261HB0 from Siemens is used for current-dependent overload protection in the main circuit. Thanks to its wide setting range of 5.5-8 A, the SIRIUS overload relay 3RU21261HB0 provides optimum protection for motors and systems up to 3 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 3RU21261HB0 can be perfectly integrated into the load feeder. Monitoring relays are used in all areas of electrical switchgear technology.
