Product questions
What coil voltage does ABB 1SAE231111R0631 require?
The ESB25-31N-06 has a 230–240 V AC/DC control coil. Check the control supply and the complete part number before ordering; other versions have different coils.
How many contacts does the ESB25-31N-06 have?
It is a four-pole contactor with three normally open and one normally closed main contact. Verify that this contact arrangement matches the circuit being controlled.
Can this 25 A contactor switch a motor load?
Its 25 A rating applies to AC-1 and AC-7a; motor duty uses different ratings. For AC-3 at 400 V three-phase, the normally open contacts are rated 9 A and 4 kW. Verify the motor load and duty before selection.
How is the ESB25-31N-06 mounted and protected?
It mounts on a DIN rail and occupies two modular spaces. Its stated degree of protection is IP20; assess the installation environment and enclosure requirements separately.
Is this contactor a replacement for my existing unit?
Check the existing part number, contact configuration, control voltage and load ratings. If it is installed in equipment, provide the equipment model and serial number for verification; compatibility cannot be assumed.
