## Overview

The AS3-NOAC-FT is a US-made, solid-core AC current sensing switch featuring jumper-selectable input ranges from 1 to 175 amps and a potentiometer-adjustable setpoint. Its self-powered, normally-open solid-state output minimizes installation costs, while the FT-style enclosure with top terminals ensures easy integration. Certified UL, CE, and RoHS compliant, it’s engineered for reliable amperage monitoring in industrial applications like stalled motor detection.

## Description

This NK Technologies AS3-NOAC-FT current-sensing switch has an FT-style case with a solid-core enclosure and top-located terminals and AC output for use in AC current-monitoring applications. It is made in the USA. The switch has a potentiometer-adjustable setpoint with jumper-selectable 1-6 amp, 6-40 amp, and 40-175 amp input ranges. Its solid-state normally-open (NO) contacts trigger when sensed current exceeds the setpoint. The FT-style case has a 19 mm diameter aperture and a LED indicator displays contact status. The switch has an operating temperature range of -20 to +50 degrees C. It is Underwriters Laboratories Listed (UL) and European Conformity (CE) compliant for quality assurance and complies with Restriction of Hazardous Substances (RoHS) standards. This AS3-series current-sensing switch is suitable for monitoring amperage passing through an electrical cable in applications such as detecting stalled motors in conveyor or pump applications.NK Technologies manufactures electrical sensors. The company, founded in 1982 and headquartered in San Jose, CA, meets International Organization for Standardization (ISO) standards 9001 and 14001.
