Evaluation unit for motor full protection (monostable) size S00...S12, CLASS 5...30 single installation main circuit: auxiliary circuit: spring-loaded terminal hand-automatic RESET electronic overload relay SIRIUS 3RB22 for advanced applications for current and temperature-dependent protection of consumers with normal and heavy starting against excessively high heating. Thanks to particularly large current setting ranges and different tripping 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 heating in the control cabinet. Worldwide approvals (e.g., IEC and UL/CSA) and applications in explosion-prone environments (ATEX) are standard. The devices are available with monostable or bistable output relays. Additionally, variants with communication via IO-Link are also available. All are offered with screw or spring-loaded connections for a quick, maintenance-free, and vibration-resistant connection. For each overload relay 3RB22/23/24, you will need a current sensing module 3RB29 as well as a connecting cable. Furthermore, you can optimize the auxiliary contacts for the required functionality with function extension modules. Simple, efficient, always up to date - the SIRIUS system modular concept.
