Product questions
What control voltage does the ABB ESB20-20N-14 contactor need?
The 1SBE121111R1420 has a 12 V AC/DC control circuit. The coil voltage is separate from the voltage switched by the main contacts; check both against the intended circuit.
How many contacts does the 1SBE121111R1420 have?
It is a two-pole contactor with two normally open main contacts and no normally closed main contacts. They are open when the coil is not energized.
Can the ESB20-20N-14 switch a 20 A motor load?
Do not assume the 20 A rating applies to a motor. The AC-1 and AC-7a ratings are 20 A, while the AC-3 and AC-7b ratings are 9 A at 230 V single phase. Check the motor and switching duty before selection.
How much panel space does this ABB contactor need?
The stated overall dimensions are 18 mm wide, 85 mm high and 65 mm deep. It mounts on a DIN rail and occupies one modular spacing. Check the enclosure and wiring clearances for the installation.
