Safety and hazard information
Please note that electrotechnical work may only be carried out by qualified electricians or under their guidance and supervision. Observe any deviating country-specific electrical installation standards and regulations and seek advice from a local electrician.In addition, observe more current safety instructions and regulations for the products on the manufacturer's side or the product descriptions and installation instructions on the manufacturer's side.

Devices with a connected load of > 380V/400V require a heavy current connection and may only be connected by an approved electrical company. Devices with a power rating > 12kW require the approval of your grid operator (Germany, other countries may differ).

Motor protection circuit-breaker 45A 3RV2031-4VA15 – Siemens – 4047621001883: Circuit breaker A trip 35-45A 3RV2031-4VA15 overload release current setting 35 ... 45A, setting range of the instantaneous short-circuit release 650 ... 650A, with thermal protection, sensitive to phase failure, magnetic tripping technology, rated operational voltage 690 ... 690V, rated continuous current Iu 45A, rated operational power at AC-3, 230 V 11kW, rated operational power at AC-3, 400 V 22kW, connection type main circuit screw connection, design of the actuating element rotary knob, device type built-in device fixed installation technology, with integrated auxiliary switch, number of poles 3, rated limiting short-circuit breaking current Icu at 400 V, AC 65kA, protection class (IP) IP20, height 140mm, width 55mm, depth 149mm, size S2 circuit breaker for motor protection, CLASS 10 A release 35...45 A N release 650 A screw connection Standard switching capacity with transverse auxiliary switch 1NO+1NC SIRIUS 3RV2 circuit breaker for motor protection for safe disconnection in the event of a short circuit and Protection of consumers and system against overload, s as well as for safe disconnection of the system from the mains. The compact and climate-proof circuit breakers are optimized for use in consumer feeders due to their low waste heat, of course also for IE3/IE4 motors and equally for switching direct current. Worldwide approvals (e.g. IEC and UL/CSA) and use in potentially explosive applications (ATEX or IEC Ex) are a matter of course. Device variants are available for motor protection (also with overload relay function), system protection, short-circuit protection of starter combinations, transformer protection, as main and EMERGENCY STOP switches and for use in IT networks. They are available with a screw or spring-loaded connection for a fast, maintenance-free and vibration-proof connection, and optionally with a built-in auxiliary switch. The comprehensive range of accessories, such as auxiliary switches, auxiliary releases, signaling switches, etc., is the same for all sizes. The use of various power supply options, such as the associated SIRIUS 3RV29 infeed system, reduces the main circuit wiring considerably. The 3RV2 circuit breakers replace the tried-and-tested 3RV1 series. Simple, efficient, always up-to-date - the SIRIUS modular system.
