The ZEN57 XS Relay is a unique, compact 240V Z-Wave relay, designed for tight electrical boxes where standard-size relays simply don’t fit. Whether you're outfitting a single-pole switch or upgrading a junction-box-based fixture, the ZEN57 offers a flexible, reliable solution for 120V and 240V control.
