It carries a motor-rated designation (1-1/2 hp at 120V AC, 2 hp at 240V AC), so it can handle small motor loads directly — think fan, pump, or conveyor starters in a panel — without an external contactor. The 4-pin terminal layout keeps wiring straightforward for a DPDT form. The 20 A at 600V AC rating tells you this relay can interrupt a resistive or general-use load at line voltage up to 600V — common in 480V three-phase panels where you need a compact DPDT break before the motor starter. The 30 A at 240V AC rating covers single-phase loads up to 30 A. The DC rating of 30 A at 28V DC is for low-voltage DC control circuits or battery-backed loads; DC arcs are harder to extinguish, so the 30 A cap at 28V is the practical limit. The motor-rated horsepower numbers (1-1/2 hp at 120V, 2 hp at 240V) mean it can start and run small induction motors within those power bands — useful for a 1 hp conveyor motor on 120V or a 2 hp fan on 240V single-phase. ## Durability and switching life Electrical operating durability is rated at 100,000 cycles — that is the number of load-break operations at rated current before the contacts are expected to wear out. Mechanical durability is 1,000,000 cycles, meaning the armature and spring assembly will outlast the electrical contacts by a factor of ten in a no-load or low-load application. For a relay that cycles every few seconds in a packaging line, the electrical life is the limiting factor; for occasional start-stop in a kiln control panel, it is plenty.","metaTitle":"Omron MGN2C-AC120 DPDT Relay, 120V AC Coil, 20A@600V","metaDescription":"Omron MGN2C-AC120 DPDT power relay, 120V AC coil, rated 20A@600V AC / 30A@240V AC, 30A@28V DC.
