Description

Overload relay 34...40 A thermal for motor protection size S0, CLASS 10 contactor mounting Main circuit: Screw Auxiliary circuit: Screw Manual automatic RESET SIRIUS 3RU2 thermal overload relay for current-dependant protection of consumers with normal starting against impermissible high heating due to overload or phase failure.
This series is particularly flexible and cost-effective. Worldwide approvals (e.g. IEC and UL/CSA) and applications in hazardous applications (ATEX or IEC Ex) are a matter of course.
Available with different adjustment ranges of the overload release. 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 accessories fit all sizes S00 to S3.
Simple, efficient, always up-to-date - the SIRIUS modular system.
