Product description
Overload relay Siemens SIRIUS 3RB3123-4QB0
The electronic overload relay 3RB3123-4QB0 from Siemens ensures continuous motor and plant protection. Thanks to the wide setting range of 6-25 A, the variety of types can be considerably reduced using the SIRIUS overload relay 3RB3123-4QB0. One normally closed and one normally open contact are available as auxiliary contacts. In size S0, the electronic overload relay 3RB3123-4QB0 offers optimum protection for motors and plants up to 11 kW. The power loss can be reduced by up to 98 % as compared to thermal overload relays. Monitoring relays are used in all areas of electrical switchgear technology.
