| Short Description | SIRIUS 3RN2 THERMISTOR MOTOR PROTECTION RELAY 2 C/O 24-240V | SIRIUS INNOVATION 3RT POWER CONTACTOR 3P 3NO 7A 3KW 230VAC C | AUXILIARY SWITCH TRANSVERSE 1 NO+1 NC |
| Long Description | The SIEMENS 3RN2012-1BA30 is a thermistor motor protection relay designed for panel mounting in a 22.5 mm enclosure to protect motors from overheating and circuit faults. It provides two change-over contacts and accepts a 24 V AC/DC supply, with manual, auto, or remote reset options and a test/reset button for straightforward commissioning. Built-in wire-break and short-circuit monitoring plus galvanic isolation help maintain safe operation, while two LEDs indicate ready and tripped states. Non-volatile settings and screw terminal connections simplify installation and restore configuration after power loss, making it suitable for industrial motor protection applications. | The Siemens SIRIUS 3RT2 series is a compact range of power contactors designed for switching motors and electrical loads from 7.5 kW to 55 kW at 400 V. Available in frame sizes S00, S0, S2, and S3, these contactors save panel space while providing high contact reliability, even at low switching currents. Many models include integrated auxiliary contacts, typically 1 NO and 1 NC, for straightforward control wiring. The 3RT2 series supports both screw and spring-type terminal options, offering secure, vibration-resistant connections. As part of the SIRIUS modular system, they combine seamlessly with overload relays, circuit breakers, and accessories to create complete load feeders. The devices are approved for global use under IEC and UL/CSA standards. Fail-safe versions with PLC-compatible safety inputs are also available, enabling safety applications up to SIL 3 or PL e when installed in suitable configurations. | The Siemens SIRIUS 3RV series consists of compact motor starter protectors designed to safeguard motors and electrical loads from short circuits, overloads, and phase failure. Combining thermal overload and magnetic short-circuit protection in one unit, each device trips rapidly in fault conditions and follows a Class 10 overload characteristic. The 3RV MSPs can also function as manual motor controllers or disconnect switches. Available in sizes S00 to S3, they cover rated currents from 0.11 A to 100 A for motors up to 45 kW at 400 V AC. Screw and spring-type terminal options provide secure, vibration-resistant wiring. As part of the SIRIUS modular system, they integrate easily with 3RT contactors and infeed systems to create compact load feeders with minimal wiring. The series holds worldwide approvals, including IEC, UL, CSA, and ATEX, and supports accessories such as auxiliary switches, shunt releases, and undervoltage releases for flexible control schemes. Suitable for motor protection, plant protection, and use as main or emergency-stop switches. |
