Schneider Electric RXZE2M114 RXZ Socket 4 C/O Mixed

RXZE2M114: RXZ socket for RXM relays, 4 C/O, mixed contacts

The RXZE2M114 is a Schneider Electric Harmony RXZ socket for plug-in relays. Its datasheet lists 4 C/O contacts, a mixed contact arrangement, a conventional free-air thermal current of 10 A, a width of 30 mm and screw clamp terminals. The relays it is listed for are: RXM with 2 C/O contact; RXM with 4 C/O contact; REXL with 2 C/O contact; REXL with 4 C/O contact; 782H with 4 C/O contact. Seven Star LLC supplies the RXZE2M114 in Oman and the GCC as an independent supplier based in Muscat.

Sockets are bought separately from relays, so the RXZE2M114 is typically ordered together with a matching RXM relay such as the RXM4AB2BD or RXM4LB2BD, or with a relay already in use that matches the listed compatibility.

Where the RXZE2M114 is used in Oman and the GCC

In the region, sockets of this type are mostly found in control panels for pumps and compressors, building automation boards 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.

Relays that fit the RXZE2M114

The datasheet compatibility entries are: RXM with 2 C/O contact; RXM with 4 C/O contact; REXL with 2 C/O contact; REXL with 4 C/O contact; 782H with 4 C/O contact. For 4 C/O Harmony RXM relays, matching references include RXM4AB1BD, RXM4AB2BD, RXM4LB1BD and RXM4LB2BD, which differ in coil voltage and LED options. A relay with a different contact count needs a socket listed for that count, which affects wiring and rating.

Technical specifications of the RXZE2M114

Installing and maintaining the RXZE2M114

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.

The RXZE2M114 among RXZ sockets

The RXZ range includes mixed and separate-contact versions, different widths and screw clamp or screw connector terminals. The table shows the references covered in this group.

Mounting the RXZE2M114

The datasheet lists two fixing methods: by screw on a panel, or clip-on on a 35 mm symmetrical DIN rail. The body is 30 mm wide and weighs 0.051 kg net. Where the relay will see vibration, a metal maintaining clamp like the RXZ400 can retain it in the socket, and the 18-month warranty listed applies to the socket itself.

Degree of protection is listed as IP20 conforming to IEC 60529 Dielectric strength 2500 V, so the socket is meant for the inside of a panel, not exposed locations.

Wiring the RXZE2M114: screw clamp terminals

The terminal section of the datasheet lists the conductors the this part accepts:

• Screw clamp terminals, 1 × 0.34–1 × 1 mm² (22 AWG–17 AWG) flexible with cable end
• Screw clamp terminals, 2 × 0.34–2 × 1 mm² (22 AWG–17 AWG) flexible with cable end
• Screw clamp terminals, 1 × 0.5–1 × 1.5 mm² (20 AWG–16 AWG) solid without cable end
• Screw clamp terminals, 2 × 0.5–2 × 1.5 mm² (20 AWG–16 AWG) solid without cable end

Tighten to < 1 N.m for M3 screw(s) on M3 screws and strip 8 mm as listed. Cable ends on flexible conductors are the normal practice, and the datasheet differentiates the sizes allowed with and without ferrules.

Information to send with an RFQ for the RXZE2M114

• 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.
