The trip range spans 2 to 500 mA AC/DC, so it catches both undercurrent (pump dry-run, belt slip) and overcurrent (load jam, shorted winding) conditions on a motor or heater circuit. The adjustable delay from 0.1 to 30 seconds lets you ignore inrush or transient spikes — set it long enough that the relay doesn't nuisance-trip on a motor start, short enough that a true fault still gets caught before the line goes down. ## Ratings that decide the fit Supply voltage is 200–230 VAC — common for European and Asian control panels running on a 220 V or 230 V phase-to-neutral rail. The relay output is rated 6 A at 250 VAC, enough to switch a contactor coil or a small motor starter directly without an interposing relay. Mounting is DIN rail, so it clips onto a standard 35 mm rail inside the panel. The operating range of -20°C to 60°C covers most indoor industrial environments, though you'll want to keep it out of direct heat from a drive or transformer if the cabinet runs near the upper limit. ## Lifecycle reality — obsolete, sourced to order Omron lists the K8AB-AS1 200/230VAC as obsolete. That means the factory no longer builds it, and the only channel for new-old-stock or surplus units is independent distribution. We source this part against an RFQ — quantities are confirmed at quote time, and the price reflects the surplus market, not a catalog list.","metaTitle":"Omron K8AB-AS1 200/230VAC Current Sensing Relay, 2-500mA","metaDescription":"Omron K8AB-AS1 200/230VAC current sensing relay, SPDT output, trip range 2-500mA AC/DC, adjustable delay 0.1-30 sec.
