Schneider Electric F10NOR Auxiliary Contact Block

The Schneider Electric Telemecanique F10NOR Auxiliary Contact Block adds a single normally open auxiliary contact to compatible Telemecanique contactors, enabling signaling and electrical interlocking in motor control and automation circuits. This front-mounted accessory uses screw clamp terminals for straightforward wiring and delivers instantaneous contact operation with a rated insulation voltage up to 690 VAC. Commonly installed in motor control centers, control panels, and conveyor systems, as well as industrial machinery and manufacturing equipment, the F10NOR supports auxiliary control, signaling, and interlocking circuits and helps indicate equipment status within control logic. It is a standard replacement part for signaling and control interlocks across automation installations, often used by maintenance teams, OEM engineers, and system integrators for control panel assembly, equipment maintenance, retrofit projects, and system upgrades. Common replacements include Schneider Electric LADN10 Auxiliary Contact Block, Allen-Bradley 100-S, and Siemens 3RH1921.
