NEW ARRIVAL: Siemens SIRIUS 3RH2911-1XA40-0MA0 Auxiliary Contact Block Available Immediately
Model Description
We are pleased to announce the immediate availability of the Siemens SIRIUS 3RH2911-1XA40-0MA0 auxiliary contact block, a premium signaling component designed for seamless integration with 3RT2 contactors and 3RH2 contactor relays. This front-mounted snap-on block features 2 normally open (NO) contacts in a compact 45mm x 63mm x 37.5mm housing, providing reliable status feedback for motor control applications. The unit utilizes robust screw terminal connections supporting conductor cross-sections from 0.5 to 2.5 mm², ensuring secure wiring in vibration-prone environments. Designed for tool-free installation, the snap-on mounting mechanism allows field technicians to attach the block to contactors without removing primary wiring, significantly reducing maintenance downtime. The 3RH2911-1XA40-0MA0 is engineered for universal compatibility across S00, S0, and S2 frame sizes, enabling standardized inventory management for diverse control panel configurations.
Key Features
The 3RH2911-1XA40-0MA0 delivers exceptional electrical performance with AC-15 operational ratings of 6A at 250V and DC-13 ratings of 6A at 24V. Contact reliability achieves IEC 60947-5-1 requirements with mechanical endurance exceeding 10 million operating cycles and electrical life of 200,000 cycles at rated load. Operating temperature range spans -25°C to +60°C, with surge voltage resistance of 6kV ensuring robust protection for auxiliary circuits. The block meets IP20 finger-safe protection standards and carries CE, UL, and CCC certifications for global deployment. Contact switching time remains below 20ms, providing rapid status indication for time-critical interlocking schemes. The gold-plated contact surfaces minimize oxidation and ensure reliable low-current signal transmission down to 17V at 1mA, making it ideal for modern electronic control systems and PLC input interfacing.
