Product questions
What coil voltage does the ABB ESB25-31N-07 require?
Its rated control voltage is 400–415 V AC or DC. This is the control supply rating, not the main-circuit load voltage; check the available control supply before ordering.
What contacts does the 1SAE231111R0731 have?
It is a four-pole contactor with three normally open and one normally closed main contact. Check the required contact arrangement against the existing circuit.
Can this contactor switch a 400 V three-phase motor?
Its published AC-3 rating is 4 kW and 9 A at 400 V three-phase on the normally open contacts. The 25 A rating applies to AC-1 duty, not automatically to motor switching. Check the motor and circuit requirements before selection.
What are the dimensions and protection rating of this contactor?
The net dimensions are 36 mm wide, 85 mm high and 65 mm deep; the published protection rating is IP20. Allow for the enclosure and installation requirements when checking space.
