Description:
These pilot devices are for use with Siemens starters and
contactors mounted in NEMA Type 1 clamshell enclosures.
The start- stop pushbutton provides a momentary 3-wire type
of control. The selector switches provide a maintained 2-wire
type of control. In the AUTO position of the hand-off-auto
selector switch, a remote pilot device such as a pressure switch
or a thermostat can be wired to give automatic control for the
starter or contactor.
Contents of Kit: Pilot device, legend labels, wires, support bracket
and mounting screws.
