Overload Relay, 32-115A, for Motor Protection, S3, CLASS 5E-30E, Contactor Mounting – 3RB31434XB0

Overload relay 32...115 A electronic for motor protection Size S3, CLASS 5E...30E Contactor mounting Main circuit: screw Auxiliary circuit: screw Manual-automatic RESET Electronic overload relay SIRIUS 3RB3 for current-dependent protection of loads with normal and heavy starting against impermissibly high heating due to overload, phase unbalance or phase failure. Thanks to wide current setting ranges and different trip characteristics, entire series of motors can be covered with just a few types. With their low power loss, they are particularly energy-efficient and contribute to lower heat generation in the control cabinet. Worldwide approvals (e.g. IEC and UL/CSA) and applications in hazardous areas (ATEX) are a matter of course. The 3RB31 version offers extended functionalities such as an integrated electrical remote reset, ground fault detection and much more. Available with different setting ranges for the overload release and with different trip 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 accessories are consistently suitable for all sizes S00 to S3. Simple, efficient, always up-to-date - the SIRIUS modular system.
