Product questions
What control voltage does the ABB ESB20-02N-06 contactor require?
The rated control voltage is 230 V AC/DC. Check the control supply and the marking on the existing device before selecting a replacement; the control voltage is distinct from the main circuit voltage rating.
Are the contacts on 1SBE121111R0602 normally open or normally closed?
This two-pole contactor has two normally closed main contacts and no normally open main contacts. Verify the required contact arrangement before replacing an existing contactor.
Can the ESB20-02N-06 switch a 20 A motor load?
Not on the basis of its 20 A rating alone. Its NC contacts are rated 20 A in AC-1 and AC-7a, but 9 A in AC-3 and AC-7b at 230 V single-phase. Confirm the load, duty and protection requirements before selection.
What main circuit voltage is the ESB20-02N-06 rated for?
The listed main circuit operational voltage is 250 V AC or 220 V DC. The permissible switching current depends on the load and operating conditions, so the voltage rating alone does not establish suitability.
