Product questions
What coil voltage does the ABB EN20-20N-01 require?
The control coil is rated at 24 V AC or DC. This is the control voltage, not the main-circuit voltage.
How many contacts does 1SBE122111R0120 have?
It has two poles with two normally open main contacts and no normally closed main contacts. No auxiliary contacts are listed as built in.
Can this contactor be operated manually?
Yes. The EN20N has a built-in toggle for manual or automatic operation and integrated overvoltage protection.
Is the EN20-20N-01 rated for a 20 A motor load?
Not universally. Its normally open 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. Check the load and utilization category before selection.
What mounting and dimensions should I check?
The contactor fits TH35-7.5 or TH35-15 DIN rail. Its listed net dimensions are 18 mm wide, 85 mm high and 65 mm deep. Confirm available enclosure space before ordering.
