Schneider Electric RXZE1M4C RXZ relay socket, 7 A, screw clamp

RXZE1M4C: RXZ socket for RXM2LB and RXM4LB relays, 7 A, screw clamp

The RXZE1M4C is a Schneider Electric Harmony Electromechanical Relays socket of the RXZ family, built for RXM plug-in relays with two or four changeover contacts (RXM2LB and RXM4LB). It has screw clamp terminals in a mixed arrangement, a 7 A thermal current rating, and fixes either by screw on a panel or clipped on a 35 mm DIN rail. Seven Star LLC supplies the RXZE1M4C in Oman and the GCC as an independent supplier in Muscat.

Reading the reference: RXZ is the socket family, and the title gives the relay compatibility, the current rating and the terminal style. The datasheet used here is dated 8 Nov 2026 and carries no lifecycle notice. It is sold in indivisible quantities of 10.

Which relays fit the RXZE1M4C

The datasheet lists plug-in relay RXM with 2 C/O contacts and plug-in relay RXM with 4 C/O contacts as compatible. The socket itself is shown with 4 C/O contacts, meaning it provides the terminals for a 4-pole relay and can also take a 2-pole relay. A relay and socket should be chosen as a pair: relay coil voltage, contact current and socket current rating must all suit the load.

Do not mix families. RXZ is the socket family for the RXM relays; a socket for another relay series will not fit, even if it looks similar. When replacing a relay, replace its holding clip if it has lost tension.

Technical specifications of the RXZE1M4C

Terminals and wiring of the RXZE1M4C

The screw clamp terminals accept 1 or 2 x 0.2–1.0 mm² flexible conductors with a cable end, or 1 or 2 x 0.5–1.5 mm² solid conductors without. Tighten M3 screws to below 0.8 N.m. The mixed terminal arrangement places coil and contact terminals in a defined pattern, so follow the wiring diagram printed with the product and in the datasheet.

Use cable ends on stranded wire to keep strands from spreading, and keep coil wiring separated from contact wiring where voltages differ. Each terminal clamp holds two conductors if both are the same type and size; mixing a solid and a flexible conductor under one clamp is not recommended.

Mounting and size of the RXZE1M4C

The socket is 29 mm wide and weighs 0.053 kg. It clips onto a 35 mm symmetrical DIN rail or is fixed by screw to a panel. DIN-rail mounting is the usual choice in control cabinets, with sockets placed side by side at the width of 29 mm. In vibrating locations, use end stops on the rail so the sockets cannot slide.

Leave space around hot components. The datasheet gives -40 to 55 °C for operation and -55 to 85 °C for storage, and a relay coil adds its own heat to the socket in a densely packed row.

Ratings and approvals for the RXZE1M4C

The conventional thermal current is 7 A and rated operational voltage is 250 V AC. The impulse withstand voltage is 4 kV and the dielectric strength 2500 V, in overvoltage category III and pollution degree 3. Standards listed are IEC 61984, CE and UL 508.

The socket current rating can be lower than the contact rating of the relay, so the circuit must respect the lower of the two. Environmental data show a total lifecycle carbon footprint of 0.7 kg CO2 eq. and a recyclability potential of 48 %.

Maintenance and spares for the RXZE1M4C

RXZ sockets are passive parts, so maintenance means keeping them tight, clean and cool. At each shutdown, re-torque the M3 terminal screws, look for browning of the plastic near the contact terminals, and make sure the relay seats fully. A socket that has overheated should be replaced rather than cleaned, because the terminal spring can lose temper.

Keep a few spare sockets with the relays in the panel spares kit, and note the reference this unit in the panel records so it can be matched quickly. The datasheet shows no lifecycle notice, but availability should still be confirmed at the time of ordering.
