Product questions
What control voltage does ABB 1SAE231111R0204 require?
The ESB25-04N-02 has a rated control voltage of 42 V AC/DC. Do not confuse the control voltage with the main-circuit voltage; confirm the control supply before ordering.
How are the contacts configured on the ESB25-04N-02?
It has four normally closed main contacts and no normally open main contacts. Check that this contact arrangement matches the control circuit before selecting it.
Can this 25 A contactor switch a motor load?
The 25 A rating applies to AC-1 loads, not every motor duty. For AC-3, the listed rating is 6 A at 230 V single-phase, with 0.9 kW at 230 V single-phase and 2.7 kW at 400 V three-phase. Check the motor and operating conditions against the applicable ratings.
How much panel space does the ESB25-04N-02 need?
The contactor measures 85 mm high, 36 mm wide and 65 mm deep. Its width is two modular spacings; ABB also lists a built-in depth of 58 mm. Check the enclosure and clearances before installation.
