Siemens SIRIUS Contactor Relay, Latched 2 NO + 2 NC –
3RH2422-1BF40
The Siemens 3RH2422-1BF40 is a SIRIUS series
contactor relay with mechanical latching function, designed for reliable
switching and control operations in industrial automation and control
circuits. It is widely used in control panels, automation systems, motor
control circuits, and interlocking applications where stable contact
positioning and low control power consumption are required.
This model features a 2 NO + 2 NC contact configuration,
providing flexible switching capability for auxiliary control and signaling
applications. The latched (mechanically maintained) operation ensures
that the contact position is retained even after control voltage removal, making
it suitable for energy-efficient and memory-retention switching applications.
The relay is designed with a compact SIRIUS industrial
control platform, offering dependable performance, long electrical life,
and easy integration into industrial control panels.
