Product questions
What control voltage does the ABB ESB25-04N-06 contactor use?
The ESB25-04N-06 has a 230–240 V control circuit and can be operated with AC or DC. Check the control supply separately from the main-circuit voltage before selection.
Are the contacts normally open or normally closed?
This four-pole version has four normally closed main contacts and no normally open main contacts. The contacts open when the coil is energised.
Is the 25 A rating suitable for every load on the ESB25-04N-06?
No. The 25 A rating is listed for utilization category AC-1; the appropriate rating depends on the load and operating conditions. Check the specific utilization category and voltage before selecting the contactor.
How much modular panel space does the ESB25-04N-06 need?
The contactor occupies two modular spacings. It is designed for DIN-rail mounting; confirm enclosure space and installation clearances for the intended panel.
