Overload relay 55...250 A for motor protection Size S10/S12, CLASS 10E Contactor attachment/single installation Main circuit: Rail connection Auxiliary circuit: Screw connection Manual-automatic RESET Electronic overload relay SIRIUS 3RB2 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 lower 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 various setting ranges for the overload release and with various release 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 S6 to S12. Simple, efficient, always up-to-date - the SIRIUS modular system.
