Product details

Product Overview and Key Ratings

That 10 A rating at 230 V is the headline figure for general-purpose control loads; the contactor also carries derated values for higher voltages: 3 A at 400 V, 1 A at 690 V, and 0.26 A at 600 V. For DC switching, the contacts handle 10 A at 24 V, 4.7 A at 60 V, and 1.2 A at 220 V. These ratings are per the datasheet and define the maximum continuous current the contacts can make and break at the stated voltage under the specified duty. The contactor uses the S00 frame size. Dimensions: 70 mm high, 45 mm wide, 73 mm deep.

Rated for pollution degree 3. Relative humidity minimum is 10 %. Substance prohibition date is 10/01/2009.

These are the minimum air gaps needed to maintain rated insulation and to allow heat dissipation. The S00 frame width of 45 mm means it occupies three DIN rail module spaces (one module = 15 mm). When wiring, the screw terminals accept 2x (0.5 to 4 mm²) solid or stranded conductors — sufficient for control-circuit wiring up to 4 mm².

Switching Performance

Mechanical life is typical 30 million operating cycles. Maximum operating frequency for DC switching is 10,000 operations per hour.
