How to use
The ABB ESB25-04N-06 is designed for mounting on a standard DIN rail within a distribution cabinet. Ensure that the power supply is disconnected before installation. Connect the control circuit to the coil terminals and the load circuit to the main power terminals, ensuring that the wiring matches the electrical diagram provided with the device. Once installed, the contactor will automatically manage the connected load based on the control signal received.
What to consider before purchase
Verify that the 4NC contact configuration meets your specific circuit requirements.
Ensure the control voltage of 230-240V AC/DC is compatible with your control system.
Check the available space in your distribution board for DIN rail mounting.
Confirm that the 25A rated current is sufficient for your intended electrical load.
