AC current switches offer fixed or adjustable trip points, sensing ranges up to 400 Amps, fixed- or split-core mounting styles, and a variety of features such as a digital setpoint display, solid-state outputs, or field-adjustable time delayed outputs to minimize nuisance trips.
AC current switches combine a current transformer, signal conditioner, and limit alarm into a single package for monitoring AC applications. They use fixed or adjustable setpoints to provide discrete outputs based on the input current level and offer the following advantages:

ACSN series fixed range current switches provide simple current flow status indication with no setup required.
ACS150 series AC current switches offer an adjustable trip point, universal solid-state outputs, and accurate indication of overcurrent conditions across a broad range of applications.
ACS200 series solid-state current switches operate when the current level through the sensing aperture exceeds the adjustable setpoint. Internal circuits are powered by induction from the line being monitored.
ACS035/ACS400 series current switches feature two separate, field-adjustable setpoints for overcurrent and undercurrent monitoring in a single device. With SPDT relay outputs, the sensors provide a control output and a status output for remote monitoring systems.
ACS050/ACS200 series current switches feature easy and precise setpoint adjustment via a single-turn potentiometer and a three-digit LED display.
ACSL series self-powered, single-range current switches feature easy setpoint adjustment via a 3/4-turn potentiometer and an integrated time delay function.
ACSX series high-performance current switches include an adjustable 0-15 second start-up delay timer to eliminate nuisance alarms due to inrush or temporary over-current conditions.
