Schneider Electric's Square D 9050-MER30 On Delay Relay provides a precise, time-delayed output for control circuits, enabling downstream devices to energize only after a defined interval when power or a control signal is applied. The MER30 variant specifies a timing window from 1.5 to 30 seconds and operates on a 110 V alternating current supply compatible with 50 Hz and 60 Hz systems. As part of the 9050 family of general‑purpose timing relays, this device is used to sequence relays, contactors, alarms, or other control elements in industrial panels where reliable, repeatable on-delay timing is required.
