Relay (electric relay)

The Siemens SIRIUS 3RH2911-1DA02 is a side-mounted auxiliary switch with 2 normally closed (2 NC) contacts and screw terminal connections. It is specifically designed for side mounting of 3RT2.1 (S00) contactors, without occupying the front space of the contactor, and is suitable for control circuits that require the front position to be retained.

The Siemens SIRIUS 3RH2911-1BA01 is a single-pole front-mounted auxiliary switch with one normally closed (1 NC) contact, terminal markings 71/72, bottom entry, screw terminal connection, and can be snapped onto the front of the 3RT2 contactor and 3RH2 contact relay to expand single-point control signals.

The Siemens SIRIUS 3RH2911-1AA10 is a single-pole front-mounted auxiliary switch with one normally open (1 NO) contact, terminal markings 73/74, top-entry wiring, screw terminal connection, and can be snapped onto the front of the 3RT2 contactor and 3RH2 contact relay to expand single-point control signals.

The Siemens SIRIUS 3RH2440-1AP00 is an S00 latching contact relay with 4 normally open contacts, an AC 230V 50/60Hz coil, and screw terminal connection. After the coil is activated, the contact state is maintained by mechanical latching, making it suitable for circuits that need to remember the control state.

The Siemens SIRIUS 3RH2440-1AF00 is an S00 latching contact relay with 4 normally open contacts, an AC 110V 50/60Hz coil, and screw terminal connection. After the coil is activated, the contact state is maintained by mechanical latching, making it suitable for circuits that need to remember the control state.

The Siemens SIRIUS 3RH2431-1LW80-0LA0 is a bolt-locking contact relay for railway applications. It features 3 normally open and 1 normally closed contacts, a DC 32V coil, an operating range of 0.7–1.25 μs, a built-in varistor, screw terminal connection, and an S00 size, making it suitable for vehicle control power supplies.

The Siemens SIRIUS 3RH2431-1UW80 is an S00 latching contact relay with 3 normally open and 1 normally closed contacts, a DC 32V coil with a built-in varistor, and screw terminal connection. After the coil is activated, the contact state is maintained by mechanical latching, making it suitable for circuits that need to remember the control state.

The Siemens SIRIUS 3RH2431-1AP00 is an S00 latching contact relay with 3 normally open and 1 normally closed contacts, an AC 230V 50/60Hz coil, and screw terminal connection. After the coil is activated, the contact state is maintained by mechanical latching, making it suitable for circuits that need to remember the control state.

The Siemens SIRIUS 3RH2422-1BB40 is an S00 latching contact relay with 2 normally open and 2 normally closed contacts, a DC 24V coil, and screw terminal connection. After the coil is activated, the contact state is maintained by mechanical latching, making it suitable for circuits that need to remember the control state.

The Siemens SIRIUS 3RH2422-1AP00 is an S00 latching contact relay with 2 normally open and 2 normally closed contacts, an AC 230V 50/60Hz coil, and screw terminal connection. After the coil is activated, the contact state is maintained by mechanical latching, making it suitable for circuits that need to remember the control state.

The Siemens SIRIUS 3RH2344-1AF00 is an S00 size 8-pole contact relay with 4 normally open and 4 normally closed contacts. It comes with a detachable auxiliary switch, an AC 110V 50/60Hz coil, and screw terminal connections, making it suitable for multi-point interlocking control.

The Siemens SIRIUS 3RH2271-2BB40 is an S00 size 8-pole contact relay with 7 normally open and 1 normally closed contacts. The auxiliary switch is factory-installed, and it features a DC 24V coil and spring terminal connections. It is suitable for interlocking circuits that require a large number of control contacts.
