Qualitrol’s 900 (oil-space) and 910 (gas-space) rapid pressure rise relays actuate only briefly during a sudden-pressure event; the 909 latches that momentary signal, holds the alarm and trip circuits with LED status indication, and releases only when the front-panel reset button is pressed. It is the standard companion device for Qualitrol RPRR protection in utility substations, transformer manufacturing, and industrial power plants.\u003c\/p\u003e\u003cp\u003eThis listing is for a Qualitrol 909-300-01 with screw-terminal field wiring, listed for 24 VDC control power. The unit accepts a jumper-selectable supply, drives two output relays for simultaneous alarm and trip control, and uses a redundant make\/break input circuit that protects against false trips caused by damaged wiring.\u003c\/p\u003e\u003cp\u003eCondition: New, sealed, as listed.
