Siemens Industrial Controls 3RH2911-1HA30 Contact
The Siemens Sirius 3RH2911-1HA30 is a high-reliability, front-mounted auxiliary switch block engineered for seamless integration with SIRIUS 3RT2 power contactors and 3RH2 contactor relays. This 3-pole module features 3 Normally Open (N/O) contacts, providing essential feedback signals for PLCs, status indicators, or interlocking logic in complex control circuits. Designed for rigorous industrial environments, it supports a wide voltage range including 24/230 VAC and multiple VDC ratings up to 220V, with a rated operational current of 10A.
Built for efficiency in the field, the 3RH2911-1HA30 employs screw terminal connections for secure wiring and a tool-free snap-on mounting mechanism that significantly reduces installation time. Compatible with frame sizes S00, S0, and S2, it offers a mechanical service life of 10 million cycles, ensuring long-term stability in motor control centers and automation panels. This auxiliary block is a critical component for technicians looking to expand control logic without increasing the footprint of the primary switching device.
Key Benefits- Universal Compatibility: Fits S00, S0, and S2 3RT2 contactors, simplifying inventory for multiple service calls.
- Enhanced Logic Control: Adds three independent normally open contacts for signaling and interlocking.
- Rapid Deployment: Tool-free snap-on mounting allows for immediate field upgrades and easy disassembly via the central release lever.
- Industrial Durability: Rated for a high mechanical durability of 10 million cycles and an operating temperature range of -25 to 60 °C.
- Secure Termination: Robust screw terminals ensure reliable electrical contact even in high-vibration applications.
Which contactors are compatible with the 3RH2911-1HA30?
This block is specifically designed for the SIRIUS 3RT2 power contactors and 3RH2 relays across sizes S00, S0, and S2. It is not intended for use with the older 3RT1 series without checking specific cross-references.
Can I install multiple 3RH2911-1HA30 blocks on one contactor?
Standard 3RT2 contactors typically accept one front-mounted auxiliary block. If additional contacts are required, consider lateral-mount auxiliaries or a 4-pole front-mount variant.
What is the maximum current rating for these auxiliary contacts?
These contacts are rated for an operational current (Ie) of up to 10A at 230V AC-15, making them suitable for standard control circuit loads and pilot duties.
