Product details

Product Overview and Key Ratings

The coil is DC-operated with a rated value of 72 V, and the contactor features an extended operating range for reliable pick-up under varying control voltage conditions.

For panel layout planning, the dimensions are 55 mm width, 114 mm height, and 130 mm depth. The main contacts accept solid or stranded wire: 2x (0.5... 2.5 mm²).

Switching Capacity and Duty Ratings

The contactor's switching capacity is specified per voltage for DC-1 or similar resistive/inductive loads. At 24 V it switches 6 A; at 48 V and 60 V, 2 A; at 110 V, 1 A; at 125 V, 0.9 A; at 220 V, 0.3 A; at 400 V, 3 A; at 500 V, 2 A; at 690 V, 1 A. For motor duty at 230 V, it is rated 10 hp. The AC-4 maximum switching rate is 250 operations per hour. Mechanical endurance is typical 10,000,000 operations. Arcing time is 10... 20 ms.

Frequently asked questions

What are the key dimensions of this contactor?

Width 55 mm, height 114 mm, depth 130 mm. Required clearances: 10 mm upwards, forwards, and downwards; 6 mm at the side.

What is the rated current at 480 V and 600 V?

52 A at both 480 V and 600 V, making it suitable for motor circuits up to that current level.

Does this contactor include an auxiliary switch?

No, the standard configuration does not include an auxiliary switch. Auxiliary contact blocks are available separately if needed.
