Overload relay 3...12 A electronic for motor protection size S00, CLASS 10E contactor mounting Main circuit: Screw auxiliary circuit: Screw manual automatic RESET SIRIUS 3RB3 electronic overload relay for current-dependant protection of consumers with normal and heavy starting against impermissible high heating due to overload, phase unbalance or phase failure.Thanks to large current setting ranges and different tripping characteristics, entire series of motors are covered with only a few types. With their low power loss, they are particularly energy-efficient and contribute to lower heating in the control cabinet. Worldwide approvals (e.g. IEC and UL/CSA) and applications in hazardous applications (ATEX) are a matter of course.Available with different setting ranges of the overload release and with different tripping classes. They are available with screw or spring-type terminals for quick, maintenance-free and vibration-proof connection, as well as for stand-alone installation.The ac
