Schneider Electric RPZF2 Socket for RPM2 Relays

RPZF2 relay socket: what it is

RPZF2 is a 16 A mixed-contact socket for two-pole RPM power relays. In the Schneider Electric Harmony Electromechanical Relays range it belongs to the RPZ socket line, and the datasheet records the compatible relay as: Plug-in relay RPM with 2 C/O contact.

A socket like this is the part of a relay installation that outlasts relays: it carries the wiring, takes the clip-in relay and lets a failed relay be swapped without touching a single conductor. Sockets in this family look alike, so check the part number against the relay series and contact count before ordering.

Seven Star LLC supplies RPZF2 in Oman and the GCC as an independent industrial supplier in Muscat; the datasheet we hold is dated 8 Nov 2026.

Relays and parts that go with RPZF2

The socket pairs with RPM relays carrying 2 C/O contacts, such as RPM22BD (24 V DC) and RPM22P7 (230 V AC); the larger RPZF4 is the equivalent for the four-pole RPM relay.

For reference, the compatibility entry in the RPZF2 datasheet reads: Plug-in relay RPM with 2 C/O contact. Where a project needs a time function, the RUW101MW multifunction timer module lists sockets of the RPZ and RUZ lines as compatible; check its own datasheet for the exact sockets that apply.

Information to send with an RFQ

To quote correctly we need:

• Part number RPZF2 and the quantity.
• The relay part number that will sit in the socket.
• Wire size, ferrule use and panel or rail mounting.
• Delivery location in Oman or the GCC and any project reference.

Socket family comparison

Wiring and terminal details

The datasheet lists these conductor sizes for RPZF2: – screw clamp terminals, flexible cable with cable end 1 × 0.5–1 × 2.5 mm² / 20 AWG–14 AWG – screw clamp terminals, solid cable without cable end 1 × 0.5–1 × 1.5 mm² / 20 AWG–16 AWG – screw clamp terminals, flexible cable with cable end 2 × 0.5–2 × 2.5 mm² / 20 AWG–14 AWG – screw clamps terminals, solid cable without cable end 2 × 0.5–2 × 1.5 mm² / 20 AWG–16 AWG. Tighten to the value stated, which is < 1 N.m for M3.5 screw(s), and use ferrules on stranded wire in line with the flexible-with-cable-end entries.

The contact terminal arrangement is described as mixed and the pin shape as flat. That pin shape must match the relay, so the lockable test button on the relay is reachable from the front once it is plugged in.

Selection and ordering checklist for RPZF2

Confirm the following before you order RPZF2:

• The relay type and contact count must match: this socket is for 2 C/O RPM relays.
• Current: the datasheet gives 16 A conventional free-air thermal current and operational voltage < 250 V.
• Width on the rail: 30 mm; net weight 0.054 kg.
• Wire sizes and whether ferrules are fitted, against the terminal table above.
• Packaging: the datasheet shows a sale quantity of 10, so confirm how many you need.

Installation and maintenance notes

This unit can be fixed by panel screws or clipped onto a 35 mm symmetrical rail. The listed ambient range is -40–55 °C for operation and -40–85 °C for storage; IP20 on the socket means it belongs inside an enclosure.

Good practice is to identify each socket on the panel drawing, retorque terminals after the first thermal cycle, and inspect for discoloured terminals at routine shutdowns. A failed relay is replaced by unplugging it; the socket stays wired, which keeps downtime short.

Typical use of RPZF2 in Oman and the GCC

Typical uses are racks of power relays that switch contactor coils, solenoid valves, alarm horns and heaters in utility panels. Such panels are found in power stations, desalination plants, oil and gas facilities and building services across Oman, usually in air-conditioned rooms or sealed cabinets.

The datasheet limits operation to -40–55 °C and lists pollution degree 3 and overvoltage category III; heat build-up in sun-exposed enclosures and dust ingress through poor cable entries are the practical risks to design around.
