Fitting where a full-size switch will not, this miniature adjustable current switch proves motor status across 0.70 to 150 A and closes a normally open contact. A trip potentiometer sets the threshold anywhere in that band, so belt loss on a lightly loaded fan still registers. It takes its power from the monitored conductor, so nothing has to be run to it.

The Miniature Adjustable Current switches are designed for use in any AC current monitoring application in which you are looking for an adjustable current switch to monitor normal operating conditions, equipment failure or preventative maintenance scheduling for a Solid-Core particular piece of equipment. The adjustable current switches should be installed on the line side of the power to the motor, pump, compressor or other equipment. The miniature adjustable current switches are available in both solid and split-core versions in a smaller enclosure style than that of the A/ACS2 and A/ASCS2 Series adjustable current switches. The solid-core versions are a great choice for new installations or OEM applications in which cost sensitivity, lower trip points and environmental issues may be of concern.
