Product questions
What control voltage does ABB 1SAE231111R1440 need?
The ESB25-40N-14 has a 12 V AC/DC control circuit. The control voltage is separate from the voltage switched by the main contacts.
How many contacts does the ESB25-40N-14 have?
It is a four-pole contactor with four normally open main contacts and no normally closed main contacts.
Is the 25 A rating suitable for every type of load?
No. The 25 A rating is identified for AC-1 use; motor and other load categories require their own ratings. Check the load category and operating voltage before selection.
How is the ABB ESB25-40N-14 mounted and connected?
It mounts on a DIN rail and uses screw terminals. Its overall dimensions are approximately 36 mm wide, 85 mm high and 65 mm deep; check the available panel space before ordering.
