Product questions
What control voltage does ABB 1SAE231111R0231 require?
The ESB25-31N-02 has a 42 V AC/DC control coil. Check the available control supply and the full part number before selecting a replacement.
What is the contact arrangement of the ESB25-31N-02?
It has four main poles: three normally open (NO) contacts and one normally closed (NC) contact. The basic contactor has no built-in auxiliary contacts.
Can this 25 A contactor switch a three-phase motor?
The normally open contacts are rated for AC-3 motor duty at 9 A and 4 kW at 400 V three-phase. The 25 A rating applies to AC-1 duty, not universally to motors. Check the motor and control circuit requirements before selection.
How is the ABB ESB25-31N-02 mounted and how much space does it need?
It mounts on a 35 mm DIN rail. The product dimensions are 85 mm high, 36 mm wide and 65 mm deep; allow for the installation and wiring requirements of the panel.
Does this contactor have manual switching?
ABB lists the ESB25-31N-02 without a manual switching slider. Confirm the required operating mode and control voltage when replacing another contactor.
