MINI-ADJUSTABLE

Miniature Adjustable Status Switches (Split & Solid Core)

The A/MCS-A and A/MSCS-A are N/O solid state adjustable current switches. These switches are small in
stature, allowing for tight installations. They are ideal for providing status information on any equipment that
uses AC current. Outputs are non-polarity sensitive, N/O solid-state contacts for switching both AC and DC
circuits up to 36 volts. Units also include two Status LED indicators, which will signal three states: tripped on,
current present but below trip point, and current off or below the low end of the adjustable trip point range.
A change in current may indicate motor failure, belt loss/slippage, or mechanical failure. In any of these
events, the current can significantly increase or decrease, thus tripping the current switch and immediately
notifying the Building Management System of the failure or problem.

ORDERING

Select one Mini Current Switch (A). NOTE: LEDs should not be used to indicate whether power or current is being applied to or running through
the aperture of the sensor. Current Switches are not to be used in Life & Safety applications, or in hazardous locations.
