Product questions
What coil voltage does ABB 1SAE231111R1431 require?
The ESB25-31N-14 has a 12 V AC/DC control coil. Check the control supply separately from the voltage of the load being switched.
What are the main contact and pole arrangements?
This is a four-pole installation contactor with three normally open and one normally closed main contact (3 NO + 1 NC).
Can the ESB25-31N-14 switch a 25 A motor load?
Its 25 A rating is for AC-1; do not assume the same rating applies to motor switching. Verify the applicable utilization category, voltage and motor load against ABB’s data before selection.
How much space does this installation contactor need?
It is 36 mm wide and occupies two modular spacings. ABB lists an installation depth of 58 mm; that is not necessarily the overall product depth. Check the enclosure dimensions before ordering.
How can I check whether this contactor will replace my existing unit?
Compare the complete part number, 12 V AC/DC control supply, contact arrangement and load ratings. For equipment-specific replacement, provide the equipment model and serial number for verification; fitment has not been established.
