NEW ARRIVAL: Siemens SIRIUS 3RV2928-1A Disconnector Module Now Available
Model Description
We are pleased to announce the immediate availability of the Siemens SIRIUS 3RV2928-1A disconnector module, a critical safety accessory engineered for S00 and S0 frame 3RV2 motor starter protectors. This compact device provides visible isolation distance and lockable disconnection, enabling safe maintenance procedures on motor circuits up to 32A. The module mounts directly on the circuit breaker without increasing panel depth, while screw terminals accept 0.5–4mm² conductors for rapid installation. Measuring 45×51×30mm and weighing only 160g, the 3RV2928-1A integrates seamlessly into control cabinets, conveyor systems and OEM skids where space is at a premium and safety compliance is mandatory. The unit is maintenance-free and requires no external power supply, making it ideal for retrofit and new-build applications alike .
Key Features
The 3RV2928-1A delivers exceptional safety performance with visible contact separation that meets IEC 60947-1 isolation requirements. The lockable handle prevents unauthorized re-energisation during maintenance, while IP20 finger-safe terminals protect installers during wiring. Operating temperature spans –20°C to +70°C, and the module carries CE, cULus, CCC and RoHS approvals, ensuring global acceptance. Mechanical durability exceeds 10,000 operations, and the non-repairable design guarantees >20 years of service life. The unit is compatible with all 3RV2 accessories—auxiliary contacts, undervoltage releases and shunt trips—enabling comprehensive motor protection schemes without mechanical redesign. The front-mounted operating lever provides clear ON/OFF indication, reducing commissioning time and enhancing operator safety .
