ABB 1SBH141001R8444 Relay

ABB 1SBH141001R8444 is an auxiliary contactor in the N44E family, configured as a 4-pole device (N44E-84) used to control and interlock circuits in industrial automation. The coil is rated for 110–120 VAC, suitable for 50/60 Hz operation, aligning with ABB's 110/50 and 110–120/60 Hz specifications, making it compatible with standard US and international power systems. This model provides four main poles for switching power and four auxiliary contacts (4 NO and 4 NC) for signaling and feedback within control circuits, allowing complex logic to be implemented without drawing on the main contacts. The 1SBH141001R8444 designation places it in ABB's legacy NFC/auxiliary contactors, compatible with other N44E devices and mounting configurations. Typical applications include interlocking, sequencing, and control logic in machine controls, conveyors, and process automation where a reliable, coil-driven relay/contactor is needed to coordinate start/stop signals, safety circuits, and status indicators. The 84 suffix identifies the 4 NO + 4 NC auxiliary contacts arrangement, while 4P indicates the four main poles, enabling compact integration into control panels where space and wiring efficiency matter.
