Eaton NSB C25BNB240T Definite Purpose Contactor

The Eaton NSB C25BNB240T Definite Purpose Contactor is a 2-pole, non-reversing device with a 24 V coil and a 40 A rating, designed to switch electrical loads in control circuits. With a 50/60 Hz rating, the coil operates on standard AC supply, making it suitable for general industrial control panels where a reliable, low-voltage coil is used to energize a contactor that carries larger line currents. The definite purpose designation indicates this unit is built for a defined control task rather than general-purpose motor starting; the 2-pole configuration provides two isolated current paths to control a circuit cleanly and efficiently, while the non-reversing design means it does not support reversing the connected load’s direction. The NSB family from Eaton is known for compact form factors and dependable performance in control applications; this model combines durable contact materials with a coil that energizes with a 24 V control signal, enabling straightforward integration with standard 24 VAC control circuits. When selecting a contactor, this part satisfies requirements for a compact, single-direction switching device capable of interrupting or energizing loads up to 40 A while operating from a 24 V control coil, offering a straightforward solution for automation and control schemes where a definite purpose interface is appropriate.
