Specifications & build — Part No.: FLS820-012-1C; 12 VDC coil (standard ~80 Ω); contact form 1C (SPDT) 5-pin; rating: NO 40 A / NC 30 A @13.5 V; max operating voltage 27 VDC; operate/release ≤10/≤5 ms; insulation ≥100 MΩ; mechanical life ≥1×10⁶ operations; electrical life ≥1×10⁵; ambient −40–85 °C; quick-connect blade terminals; case ≈25.0×27.4×28.4 mm; options include parallel resistor (12 V≈680 Ω) or flyback-diode variants. Built for the Mini-ISO footprint.
Installation & location — Plug-in 5-blade Mini-ISO footprint with molded bottom numbering: 30 (common), 85/86 (coil), 87 (N.O.), 87a (N.C.). Compatible with 12 V fuse/relay boxes typically located under-hood or in-cabin; match the pin layout and coil suppression of the original. Disconnect battery, pull old relay straight up, seat this relay fully; confirm TYPE B pin orientation before power-up.
Compatibility rules (use as fitment text) — Compatible with 12 V vehicles/equipment that specify a Mini-ISO Form C 5-pin relay (TYPE B pin layout) rated 40/30 A, terminal IDs 30-85-86-87-87a, case ≈25×27.4×28.4 mm. If your original relay matches footprint, pinout and ratings, this is a direct plug-in. Not for Micro-280 relays or 24 V systems. Use an appropriately sized fuse and wiring for the circuit load.
Typical applications & faults addressed — Compatible with control of fuel pump, radiator/condensor fan, A/C compressor clutch, auxiliary lighting/horns and other high-load 12 V circuits. Replacing a sticking/burnt relay can restore fuel-pump prime/no-start, fan not engaging, inoperative A/C clutch or intermittent lighting when the rest of the circuit tests good.
Complementary items for related traffic — Compatible with 5-pin Mini-ISO relay sockets/harnesses (30/85/86/87/87a) and weatherproof relay boxes; pair with an inline ATC/ATO fuse holder sized for the load. Searching “Mini ISO 5-pin relay connector” or “waterproof relay harness” will surface suitable sockets and pigtails.

Where It FitsCompatible with 12V vehicles and equipment that use a Mini ISO 5-pin SPDT relay in the fuse/relay box. Typical circuits include fuel pump, radiator/condenser fan, A/C compressor clutch, auxiliary lighting and horns.
How to Confirm CompatibilityMatch the pin layout: TYPE B Mini ISO bottom numbering 30–85–86–87–87a.
Verify coil voltage is 12V and the relay is rated ~40/30A.
Check the case size and that your socket accepts a 5-blade Mini ISO relay.
Installation NotesDisconnect the battery. Pull the old relay straight up from the socket.
Insert this relay fully; ensure seating and orientation match the diagram.
Use an appropriately sized fuse and wiring for the load.
