CONTACTOR ESB 4NO 25A 24VAC/DC

The new ESB_N and EN_N relay series operates silently with AC and DC control.
The new ESB_N and EN_N product series, which is broader and more technologically advanced than its predecessor, differs from the previous series in many ways. All products in the new series can be controlled with AC and DC control voltage, resulting in a very small number of part numbers and straightforward logistics management. The front panel features a green/red status indicator that is clearly visible from the side for enhanced safety. The AC/DC controlled coil of the contactor operates silently, making it suitable for installation in locations such as a control panel mounted on a hotel room wall. Typical applications for the ESB_N series include various building controls such as HVAC units, LED lighting, renewable energy controls, and charging stations. The ESB series has been extended both downward and upward, now covering a current range of 16 A to 100 A. The product series now also comply with the industrial standard IEC 60947-4-1 as well as IEC 61095. There are a total of eight varistor-protected AC/DC control coils ranging from 24 V to 415 V. ESB_N product series: 16 A - 100 A / AC-1, AC-7; width 1 - 6 modules. EN_N product series: 25 A - 40 A / AC-1, AC-7; width 1 - 3 modules. Front cover control switch: OFF - 0, AUTO, ON - I. Two auxiliary contact options are available for the series, compatible with the entire range. Contact options 1 S + 1 A or 2 S are installed without tools on the left side of the devices. The sealing cover is full-depth. This product description is an automated translation of the original Finnish description.
