Multiple monitoring modes This switch supports normally open (M3050) and normally closed (M3056) operation, providing flexible monitoring of current levels. Red and green indicator lights give immediate visual feedback on status, so you can quickly assess your system performance. Wide current range Designed to monitor currents from 2 A to 30 A. The threshold is adjustable to suit specific applications and electrical setups. Fast response time A noncontact electronic switch design enables fast response and reliable operation for quick electrical control without relying on mechanical switching. Construction Manufactured from environmentally friendly flameretardant PC material. The switch is safe for use in various environments and features a robust design that supports longevity and reliability under demanding conditions. Use scenarios Industrial automation and machine control: monitor and control current loads such as motors or heaters with clear status indication. Power supplies and battery charging: observe charging or supply currents with an adjustable threshold to prevent overcurrent conditions. Building automation and safety systems: integrate into panels or safety circuits where fast, visible current monitoring is beneficial.
