Product Description

Siemens 7RQ0100-0CR00 Plug-In Relay – 3CO, 11-Pin, 10A, 230V AC

The Siemens 7RQ0100-0CR00 is a SINOVA 7RQ plug-in relay with 3 changeover contacts (3CO), an 11-pin configuration, and a 10 A contact rating. The exact article is designed for a 230 V AC control supply and includes an LED indicator across the coil. Siemens' official selection and ordering data identifies this article in the 3 CO, 10 A, 11-pin relay family.

Siemens 7RQ0100-0CR00 Plug-In Relay

The 7RQ0100-0CR00 belongs to the Siemens SINOVA 7RQ plug-in relay family for industrial control, switching, signalling and auxiliary circuit applications.

It provides three changeover contacts in one compact plug-in relay, allowing multiple independent switching functions to be handled from a single control signal.

Siemens identifies the 7RQ0100-0CR00 specifically as the 230 V AC version of the 3CO, 10 A, 11-pin relay family.

230 V AC Control Supply

The exact 7RQ0100-0CR00 is designed for a 230 V AC control supply.

Siemens lists the AC variants in the same 3CO, 10 A, 11-pin family as:

• 6 V AC – 7RQ0100-0CK00

• 12 V AC – 7RQ0100-0CL00

• 24 V AC – 7RQ0100-0CM00

• 48 V AC – 7RQ0100-0CN00

• 110 V AC – 7RQ0100-0CP00

• 115 V AC – 7RQ0100-0CQ00

• 230 V AC – 7RQ0100-0CR00

The relay coil should be connected to the specified 230 V AC control supply.

3 Changeover Contacts

The relay provides 3 changeover contacts (3CO).

Each changeover contact provides a common connection that switches between normally open and normally closed paths according to the relay state.

Three changeover contacts can support several control functions from one relay, including:

• Control-circuit switching

• Auxiliary switching

• Status indication

• Signal transfer

• Electrical interlocking

• Alarm circuits

• Machine-control circuits

The actual connected load must remain within the applicable relay specifications.

11-Pin Configuration

The 7RQ0100-0CR00 uses an 11-pin configuration. Siemens' official product data identifies the entire 3CO, 10 A relay family as 11-pin.

The relay should be installed in the corresponding Siemens socket with the correct mechanical and electrical configuration.

The compatible socket listed by Siemens for the 3CO, 10 A relay family is:

7RQ0201-1CX00 – DIN rail mounting socket

10 A Contact Rating

The 7RQ0100-0CR00 belongs to the 3CO, 10 A relay category.

The actual switching capability should be evaluated according to the connected load, operating voltage, switching category and complete circuit conditions rather than relying only on the nominal current rating.

LED Indicator Across Coil

The relay includes an LED indicator across the coil. Siemens specifies this as a standard feature of the 3CO, 10 A, 11-pin relay family.

The LED provides a convenient visual indication when the relay coil is energized and can assist with:

• Panel inspection

• Maintenance

• Troubleshooting

• Relay-status identification

Plug-In Construction

The 7RQ0100-0CR00 uses a plug-in construction, allowing it to be installed into a compatible relay socket.

This arrangement can simplify:

• Relay replacement

• Preventive maintenance

• Panel servicing

• Troubleshooting

• Spare-part replacement

The fixed socket wiring can remain in place while the relay is replaced.

Compatible Relay Socket

For the 3CO, 10 A, 11-pin relay family, Siemens lists:

7RQ0201-1CX00 – DIN rail mounting socket

The relay and socket should be checked together for correct mechanical and electrical compatibility.

Industrial Control Applications

The 7RQ0100-0CR00 can be considered for compatible applications such as:

• Industrial control panels

• Electrical cabinets

• Machine-control systems

• Process-control circuits

• Relay interface systems

• Equipment signalling

• Alarm circuits

• Status indication

• Auxiliary switching

• Industrial machinery

• Maintenance and replacement applications

Multiple Switching Functions

The 3CO configuration allows one relay to provide three independent changeover switching functions.

Depending on the control-system design, these contacts can be used for:

• Multiple status signals

• Electrical interlocking

• Alarm indication

• Auxiliary control

• Signal switching

• Equipment monitoring

• Control-sequence functions

The exact contact use should follow the electrical design and load requirements.

Difference from 2CO 10A Relay

The Siemens 7RQ0110-0BR00 is a 2CO, 10 A, 8-pin, 230 V AC relay, while 7RQ0100-0CR00 is a 3CO, 10 A, 11-pin, 230 V AC relay.

Therefore, the relay contact count and socket configuration are different.

Difference from 4CO 5A Relay

The 7RQ0100-0DR00 is a 4CO, 5 A, 14-pin, 230 V AC relay, whereas 7RQ0100-0CR00 is the 3CO, 10 A, 11-pin version.

This distinction is important when selecting replacement relays and sockets.

Difference from 3CO DC Versions

Siemens also provides DC control-voltage variants in the same 3CO, 10 A, 11-pin family:

• 6 V DC – 7RQ0100-0CA00

• 12 V DC – 7RQ0100-0CB00

• 24 V DC – 7RQ0100-0CC00

• 48 V DC – 7RQ0100-0CD00

• 110 V DC – 7RQ0100-0CE00

The 7RQ0100-0CR00 is specifically the 230 V AC version.

Replacement and Maintenance

The 7RQ0100-0CR00 can be used as a replacement where an existing installation requires a 3CO, 11-pin, 10 A, 230 V AC plug-in relay.

Before ordering, verify:

• Exact relay article

• Control-supply voltage

• AC or DC operation

• 3CO contact configuration

• 11-pin arrangement

• Contact rating

• Compatible relay socket

• Existing control circuit

This avoids selecting a similar relay with a different coil voltage or contact arrangement.

The Siemens 7RQ0100-0CR00 is relevant for:

• Electrical panel builders

• Industrial buyers

• Electrical contractors

• Machine builders

• Maintenance departments

• OEM maintenance teams

• Control-panel assemblers

• Electrical product dealers

• Replacement-part procurement

For SB Smart, the product is positioned around industrial electrical product supply and procurement.

The core configuration and compatible socket are confirmed by Siemens' official 7RQ selection and ordering data.
