Overview

The ABB NF44EK-13 is an 8-pole contactor relay designed for reliable switching of auxiliary and control circuits. Manufactured by ABB Electrification, this unit features a permanently fixed 4-pole auxiliary contact block with mechanically-linked auxiliary contacts, compliant with Annex L of IEC 60947-5-1 and marked with the "Mechanically Linked" symbol. Key to its versatility is the electronic coil interface, which accepts a wide control voltage range from 24 to 500 V AC/DC (50/60 Hz). This broad coverage means only four distinct coils are needed to span control voltages from 24...500 V 50/60 Hz or 20...500 V DC, simplifying inventory and application across global standards. The NF44EK-13 effectively manages significant control voltage variations, allowing a single coil to be used worldwide without requiring component changes. Installation and wiring are significantly streamlined with the integrated Push-in Spring terminals. This innovative connection system requires only a single push for extremely fast and secure wiring, reducing installation time and effort while maintaining reliable connections. Further enhancing its utility, the NF44EK-13 includes built-in surge protection, eliminating the need for separate surge suppressor components. This integrated protection contributes to a more compact and cost-effective control panel design.
