Why Choose the NF40E-14 [1SBH137001R1440]
NF contactor relays are designed for switching auxiliary and control circuits with high reliability. They feature an electronic coil interface compatible with a broad control voltage range, from 24 to 500 V AC (50/60 Hz) or 20 to 500 V DC, covered by just four coil variants. This wide voltage tolerance allows a single coil to operate across diverse international control voltages without replacement. Integrated surge protection eliminates the need for external suppressors, enhancing system robustness. These 4-pole contactor relays are suitable for both AC and DC control circuits and are supported by a comprehensive range of accessories to facilitate flexible installation and application.
