Schneider Electric A9C30811 iTL 1P 16A Impulse Relay

The Schneider Electric A9C30811 is a 1-pole 16A iTL series impulse relay designed for bistable switching of lighting circuits, HVAC loads, and general electrical installations in commercial and industrial control panels. Operating as a latching relay, the A9C30811 retains its switched state without continuous coil energisation, making it ideal for energy-efficient staircase lighting, corridor control, and centralized building automation systems. Weighing just 218 g, this compact DIN-rail-mounted device integrates seamlessly into Acti 9 enclosures and switchboards.
