Product questions
What control voltage does the ABB ESB20-11N-14 require?
The ESB20-11N-14 has a 12 V AC/DC control coil. Its coil voltage is separate from the main circuit rating; verify the control supply before selecting a replacement.
What contacts does 1SBE121111R1411 have?
This is a two-pole contactor with one normally open and one normally closed main contact. Confirm that this contact arrangement matches the circuit being controlled.
Is the 20 A rating suitable for a motor load?
The 20 A rating applies to AC-1 and AC-7a duties. For AC-3 and AC-7b, the listed rating is 9 A at 230 V single phase for both main contacts. Check the motor and duty against the applicable rating.
What are the main-circuit voltage and physical dimensions?
The listed main-circuit operational voltages are 250 V AC and 220 V DC. The unit measures 18 mm wide by 85 mm high by 65 mm deep and occupies one modular spacing. Check the available space and circuit requirements before selection.
