Eaton NSB CE15ENS3TB Three-Phase AC Contactor

Eaton NSB CE15ENS3TB is a three-pole AC contactor designed to switch three-phase power to motors and other loads. It carries a 25 A main current rating and uses a 24 V coil that operates at 50/60 Hz, all within the E Frame family. It includes a single normally open auxiliary contact (1NO) in addition to the three main contacts, enabling simple signaling or interlock wiring in control circuits. This NSB model is identified by the CE15ENS3TB designation within Eaton's NSB line, reflecting its coil, pole count, and auxiliary contact configuration. This configuration is commonly used in industrial automation to start and stop three-phase equipment, offering a straightforward, reliable control interface in panel-mounted installations. Because the coil is rated for 24 V at 50/60 Hz, it can be driven from standard control circuits in industrial facilities.
