92S11A22D-120 Power Relay, Rep T92S11A22-120, 120VAC Coil, DPDT 2 Form C, 30A Heavy Duty 8-Terminal DIN Rail/Panel Mount, Class F Enclosed Control Relay for HVAC/Industrial Switching

92S11A22D-120 Power Relay (120VAC Coil, DPDT)This listing is for a heavy-duty power relay identified by part number OE#92S11A22D-120. It is commonly used in 120VAC control/switching circuits found in equipment control panels. Please note: the coil is 120VAC (not a 12V/24V battery coil).Key Specs (verify with your circuit)Contact form: DPDT (2 Form C / 2 C/O)Coil voltage: 120VAC; coil resistance 4.25kOhm; coil consumption 3.2-4.4VACurrent rating: 30A (NO) / 3A (NC); max switching voltage up to 300VAC/DC (UL)Mounting: DIN rail or panel mount cover; silver alloy contacts; Class F insulationOperating temperature: -40 to 55C; durability: up to 5,000,000 mechanical cycles (typical)What it doesSwitches higher-current loads using a 120VAC control signalCommon uses include blower/fan control, contactor coil control, staged heating, pumps, and general-purpose panel switching (when ratings match)Common symptoms of a failing relayIntermittent operation, relay chatter/buzzing, or delayed switchingLoads not turning on/off reliably, or visible heat/discoloration at terminalsInstallation notesDisconnect power and follow your equipment manual before replacing electrical componentsMatch terminals carefully (coil vs contacts) and tighten connections securelyAfter replacement, test operation and check for overheating during the first runFitment reminder: Confirm fitment by OE/part number (92S11A22D-120) and your equipment wiring diagram or service manual. Do not order by appearance alone.

• Specs: 92S11A22D-120 DPDT (2 Form C / 2 C/O) power relay with 120VAC coil; rated input current 30A (NO) / 3A (NC). Switching ratings include 30A @ 277VAC (NO, resistive, UL) and 30A @ 250VAC-1 (NO, IEC); max switching voltage 300VAC/DC (UL) / 250VAC/DC (IEC). Coil resistance 4.25kOhm, power 3.2-4.4VA; Class F coil insulation; silver alloy contacts; DIN rail or panel mount cover. Operating temp -40 to 55C; mechanical durability 5,000,000 cycles; electrical durability 100,000 cycles (resistive). Part No.: 92S11A22D-120 (alias W92S11A22D-120). Confirm specs against your circuit before purchase.
• Install tips: Disconnect power and follow lockout/tagout before touching wiring. Label and move wires one-by-one; match the terminal layout (coil vs contacts) to your relay diagram before tightening screws. This model uses a 120VAC coil (not a 12V/24V battery coil), so do not power it from a vehicle electrical system unless your design provides 120VAC control. Common mounting locations: HVAC/industrial control cabinet, breaker or pump control panel, or equipment relay compartment on DIN rail or a flat panel. After install, energize the coil and listen/feel for a clean click; inspect for loose terminals, overheating, or arcing on first run.
• Compatible with 120VAC HVAC air handler control board / furnace blower control circuit / heat pump control panel / rooftop unit control box (where relay model 92S11A22D-120 or an equivalent DPDT 2 Form C 120VAC coil relay is specified in the service manual or wiring diagram). Use as a replacement for switching loads such as blower motors, compressor contactor coils, electric heat staging, humidifier circuits, or other 120V control outputs when ratings match. If troubleshooting (fan won't start, intermittent operation, relay chatter), verify the part number, terminal layout, and coil voltage on the old relay before purchase Relay.
• Compatible with 120VAC industrial control panel / automation cabinet / pump controller / irrigation control box / lighting control contactor panel (where a heavy duty enclosed power relay-30A DPDT 2 Form C (2 C/O) 120VAC coil-is required). DIN rail or panel mounting supports quick replacement in crowded cabinets; silver-alloy contacts help reduce wear in frequent switching. Before ordering, confirm the coil voltage, contact form (DPDT/2 Form C), terminal style, and load type (resistive vs motor/tungsten) because inrush current can be much higher than steady-state Relay.
• Compatible with maintenance kits for 120VAC control circuits: consider keeping a spare relay of the same part number plus matching mounting hardware to reduce downtime. Helpful add-ons (verify your setup): DIN rail segment, panel screws, insulated spade/quick-connect terminals or ring lugs, wire ferrules, heat-shrink labels, and an inline fuse/holder for the control circuit. These accessories can make installation cleaner and help prevent loose connections that cause heat, arcing, or intermittent contact-always confirm your electrical design and follow the equipment manual and local electrical code Relay.
