Schneider Electric RSZE05P Harmony RSZ 12A Push-in Relay Socket

The Schneider Electric RSZE05P is a Harmony RSZ push-in relay socket for RSB1A120 plug-in relays, rated 12 A with push-in spring-clamp terminals and a separate contact arrangement. It clips onto a 35 mm symmetrical DIN rail, carries a 250 V rated insulation voltage and a 4 kV impulse withstand rating, and has an IP20 housing rating for general control-panel mounting.

Selection Notes

This RSZ socket is rated to match the RSB1A120 relay family at 12 A Ith with push-in spring-clamp terminals, no screwdriver needed for wiring, and a separate-contact terminal arrangement, clipping onto a 35 mm DIN rail. Because it carries no coil or contact rating of its own beyond the plugged-in relay, verify the mounted RSB relay's current and voltage rating rather than the socket's IP20 enclosure figure when sizing the circuit. Add the RXZ410/RXZ420 metal retaining clamp where vibration could unseat the relay. Terminals accept flexible or solid conductors from 0.5 mm² to 1.5 mm² (20-16 AWG), and the overvoltage category III, pollution degree 3 rating suits standard industrial control-panel environments without additional derating.
