Overload relay 0.32...1.25 A for motor protection Size S0, CLASS 10E Contactor attachment Main circuit: screw Auxiliary circuit: screw Manual-automatic-RESET Electronic overload relay SIRIUS 3RB3 for current-dependent protection of consumers with normal and heavy starting against excessively high heating as a result of overload, phase asymmetry or phase failure. Thanks to large current setting ranges and different tripping characteristics, entire series of motors are covered with just a few types. With their low power loss, they are particularly energy efficient and contribute to less heating in the control cabinet. Worldwide approvals (e.g. IEC and UL/CSA) and applications in potentially explosive 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-loaded connections for a quick, maintenance-free and vibration-proof connection, as well as for individual installation. The accessories are suitable for all sizes S00 to S3. Simple, efficient, always up-to-date - the SIRIUS modular system.
