Industrial ACS150-AE-S Current Switch

ACS150-AE-S is a split-core AC current switch from AcuAMP (AutomationDirect) that clamps around a single conductor to sense 1.75–150 A and switch a control circuit when the current crosses the setpoint. The adjustable trip point ranges from 1.75 to 150 A via a 4-turn potentiometer, and the device provides a solid-state normally open output rated at 0.15 A at 240 VAC or 240 VDC. It operates self-powered with no external supply required, and you can mount it on a panel or on a 35 mm DIN rail with screw-terminal connections. The unit is UL 508 listed and CE/RoHS/REACH compliant, reflecting its suitability for industrial environments. True RMS is not indicated for this current switch, as it functions as a threshold detector rather than a true RMS sensor. The ACS150-AE-S features a split-core design for convenient installation around a conductor, delivering a reliable contact output when the monitored current exceeds the setpoint.
