Product description
Overload relay Siemens SIRIUS 3RU2126-4FB0
The thermal overload relay 3RU2126-4FB0 from Siemens is used for current-dependent overload protection in the main circuit. Thanks to its wide setting range of 34-40 A, the SIRIUS overload relay 3RU2126-4FB0 provides optimum protection for motors and systems up to 18.5 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 3RU2126-4FB0 can be perfectly integrated into the load feeder. Monitoring relays are used in all areas of electrical switchgear technology.
