Schneider Electric RXZE2S108M RXZ Socket 2 C/O Separate

RXZE2S108M: RXZ socket for RXM relays, 2 C/O, separate contacts

The RXZE2S108M is a Schneider Electric Harmony RXZ socket for plug-in relays. Its datasheet lists 2 C/O contacts, a separate contact arrangement, a conventional free-air thermal current of 12 A, a width of 27 mm and screw connectors. The relays it is listed for are: RXM with 2 C/O contact; REXL with 2 C/O contact. Seven Star LLC supplies the RXZE2S108M in Oman and the GCC as an independent supplier based in Muscat.

Sockets are bought separately from relays, so the RXZE2S108M is typically ordered together with a matching RXM relay of the contact count listed above, or with a relay already in use that matches the listed compatibility.

Installing and maintaining the RXZE2S108M

Mount the this part first, wire it with the panel isolated, tighten the screws to the listed torque and then insert the relay. After commissioning, retighten terminal screws once the first thermal cycles have passed, since copper creeps and screw terminals can loosen on loads that heat and cool.

The socket outlives many relay replacements, so keep it clean and check for discoloured terminals, a sign of a loose connection or an overloaded contact, when changing relays.

Relays that fit the RXZE2S108M

The datasheet compatibility entries are: RXM with 2 C/O contact; REXL with 2 C/O contact. This socket is specifically listed for 2 C/O relays, so it is not a substitute for a 4 C/O base.

Technical specifications of the RXZE2S108M

Selection checklist for the RXZE2S108M

• Relay: confirm the relay reference is in the compatibility list (RXM with 2 C/O contact; REXL with 2 C/O contact).
• Contacts: 2 C/O.
• Current: up to 12 A thermal, with the lowest rating in the circuit governing.
• Terminals: screw connectors.
• Width: 27 mm on the rail.
• Pack: sold in indivisible quantities of 10.

Where the RXZE2S108M is used in Oman and the GCC

In the region, sockets of this type are mostly found in control panels for pumps and compressors, switchgear auxiliary and trip circuits and desalination and water treatment skids. Plug-in relays on sockets allow quick replacement during shutdowns, which is valuable where heat, dust and humidity shorten relay life.

Contact arrangement of the RXZE2S108M

The datasheet lists a separate contact terminal arrangement on this socket. The other RXZ sockets in this group include mixed versions, so the arrangement is one of the points that differ between references. The wiring diagram on the datasheet shows the numbering, which should be followed when wiring.

It is rated for 2 C/O contacts with a thermal current of 12 A, so it handles the relay contact set listed under compatibility and not other pole counts. The datasheet states pollution degree 3, overvoltage category III and a 4 kV impulse withstand, which describe the environment and supply category the socket is designed for.

Information to send with an RFQ for the RXZE2S108M

• Exact reference this part and the quantity.
• Relay reference that will sit in the socket.
• Required contacts, 2, 3 or 4 C/O.
• Preferred terminal style.
• Matching relays or retaining clamps needed in the same order.
• Delivery location and timeline.

For critical duties, keep one tested spare of every relay and base type on site, and label the shelf location in the maintenance system so that outage crews can find it quickly.

If the panel is later modified, update the drawings with the exact references fitted, because mismatches between drawings and hardware cost more time than almost any other documentation fault.

When a project is tendered with alternates, state the exact accepted references in the bill of materials, since mixed substitutions between similar-looking relays and bases are a common cause of rework at site.

Store spares in their original packaging in a dry cabinet, away from direct sun and corrosive atmospheres, so that terminals and pins stay clean until they are needed.

Where several panels use the same reference, standardising on one part number simplifies the spares list and reduces the risk of fitting the wrong version during a shutdown.

Check delivery packaging and the reference printed on the part when it arrives, so that any difference from the order is found before installation work starts.

Before ordering, check that the panel layout leaves room for heat to escape, since closed enclosures in hot rooms run closer to component limits than the rated ambient suggests.

Record the installed reference and coil or relay type on the panel schedule, because later fault investigation and replacement depend on knowing exactly what was fitted.

Keep a spare of this reference for sites that run continuously, since a like-for-like replacement keeps the original design intact after a failure.
