Product questions
What coil voltage does ABB 1SBE121111R0120 require?
The ESB20-20N-01 has a 24 V AC/DC control coil. The control voltage is separate from the voltage and current ratings of the switched load.
How many contacts does the ESB20-20N-01 have?
It is a two-pole installation contactor with two normally open main contacts and no normally closed main contacts.
Can this 20 A contactor switch a single-phase motor?
For AC-3 duty, the listed rating is 9 A and 1.3 kW at 230 V single phase. The 20 A rating is for AC-1 or AC-7a duty, not a universal motor rating. Check the motor and operating conditions before selection.
How much panel space does the ESB20-20N-01 need and how is it mounted?
The contactor is 18 mm wide, 85 mm high and 65 mm deep. It is designed for 35 mm DIN rail mounting; check available enclosure space before ordering.
