Product details

Switching capacity — what each voltage rating means for your circuit

The 3RH2440-1AK60 is rated for switching at multiple voltage levels, and the current it can handle drops as voltage rises — a common thermal/arc constraint in DC and higher-voltage AC circuits. At 24 V rated value it handles 10 A, at 230 V rated value also 10 A, but at 440 V rated value it drops to 0.5 A, and at 600 V rated value to 0.26 A. For AC-15 or DC-13 inductive loads, these are the numbers that govern contact life, not the maximum thermal current. The mechanical life is typical 5,000,000 operations, so the limiting factor in a high-cycle application will be the electrical endurance at your specific switched load.

Dimensions are 73 mm deep, 90 mm wide, 57.5 mm high — the S00 footprint that drops into a standard control panel without surprises. Relative humidity minimum 10 %.
