Product questions
What control voltage does the ABB ESB20-02N-01 require?
This version has a 24 V AC/DC control coil. Check the control supply and full part number before choosing a replacement; other ESB20 variants use different coil voltages.
Are the main contacts normally open or normally closed?
The 1SBE121111R0102 has two normally closed main contacts and no normally open main contacts. Its contact arrangement should be checked against the circuit being controlled.
Is the 20 A rating suitable for every load?
No. The 20 A rating is for AC-1 operation on the normally closed contacts. For AC-3 at 230 V single phase, the listed rating is 9 A and 1.3 kW. Select the contactor for the actual load and utilization category.
What are the dimensions and terminal type of this contactor?
The listed dimensions are 18 mm wide, 85 mm high and 65 mm deep. The contactor uses screw terminals. Check available panel space and the electrical requirements before ordering.
