    Schneider Electric RSZE1S48M – socket for Schneider Electric RSB relays, mounted on DIN rail. Screw terminals; the relay can be replaced without disconnecting wires.

  • Product description

    Relay socket | Schneider Electric RSB | 10 A | 250 V AC | DIN 35 mm | Schneider Electric RSZE1S48M

    Schneider Electric RSZE1S48M is a socket for Schneider Electric RSB relays. The relay plugs into the socket and the wires connect to the socket screw terminals, so the relay can be replaced without disturbing the wiring.

    Key point:
    A plug-in relay cannot be connected without a socket. A socket with screw terminals lets you mount the relay on a DIN rail and replace a faulty relay in seconds without disconnecting wires.
    Compatible relays
    RSB1A160…, RSB2A080…
    Rated current
    10 A / 250 V AC
    Protection class
    IP20
    Width
    15.5 mm

    Operating principle

    The socket snaps onto a 35 mm DIN rail. Coil (A1–A2) and contact wires connect to the screw terminals according to the diagram marked on the socket.

    The relay is plugged in and secured with the clip so it does not fall out due to vibration.

    When needed, the relay can be pulled out and replaced without disconnecting a single wire.

    Why choose Schneider Electric RSZE1S48M?
    Schneider Electric RSZE1S48M – a socket for RSB relays with separate terminals: coil wires on one side, load wires on the other. 15.5 mm wide, IP20.

    Main functions

    • Screw terminals – reliable wire connection in the panel.
    • DIN rail – mounting next to other modular devices.
    • Fast relay replacement – wires stay connected.
    • Marked terminals – clear coil and contact numbering.
    • Retaining clip – the relay does not fall out due to vibration.

    Where is it used?

    • Automation and control panels
    • PLC input/output interfaces
    • Industrial machinery control cabinets
    • Building automation panels
    • HVAC control panels
    • Repair and replacement of faulty relays

    Use by need

    Panel builder.
    Neat relay mounting on DIN rail with clear terminal numbering.
    Maintenance technician.
    Replace the relay without disconnecting wires – shorter downtime.
    Automation integrator.
    A standard socket that fits the whole relay series.

    Practical application

    If an interface relay fails in the panel, it is simply pulled out of the socket and a new one plugged in – the wires stay on the socket terminals, the circuit does not change and downtime is a few minutes.

    Pros

    • DIN rail mounting
    • Relay replacement without disconnecting wires
    • Clearly marked terminals
    • Separate coil and contact terminals
    • IP20, −25…+85 °C

    Cons / limitations

    • Socket current limited to 10 A even with the 16 A RSB1A160 relay
    • Fits only the specified relay series
    • Socket current is also limited by the relay ratings – the lower value applies

    Safety and installation notes

    • Install and replace relays only with the supply disconnected.
    • Tighten wires to the recommended torque; do not exceed the terminal cross-section.
    • Use only compatible relays and retaining clips.
    • Protect the socket circuit with a circuit breaker or fuse.

    Quick selection guide

    RSB
    10 A / 250 V AC
    IP20
    15.5 mm
    Suitable when you need:
    • to mount a plug-in relay on DIN rail
    • to replace relays without disconnecting wires
    • to assemble an automation panel neatly
    Check before use:
    • that the relay series fits this socket
    • wire cross-section and terminal type
    • space in the panel (width, height under the cover)
    Important reminder: a socket is not a protective device – the circuit must be protected by a circuit breaker or fuse.
