<p align="center"><b><font size="6" color="#000080">Combo Starter</font></b></p>
<p align="center"><font size="2">A COMBO starter is a starter in an
enclosure that has a <b><u>disconnect switch incorporated into the
enclosure</u></b>.</font></p>
<p align="center"><font size="2">There are many options available with a
combo starter. Below is pictured a common combo starter package. </font></p>
<p align="center"><img border="0" src="combo%20starter%20closed.jpg" width="342" height="451"></p>
<p align="left"><b>NEMA 3 Cabinet </b>- NEMA 3 indicates a cabinet that is
rain-tight. This type of cabinet is designed for outside
installations or in locations that may be wet. It has a rain lip on
the top edge and has an inner door seal to prevent moisture from entering
the enclosure. Please review the <a href="faq.htm">FAQ</a> section
to further explain the various types and applications of the NEMA 1, NEMA
3, NEMA 4 and NEMA 12 enclosures.</p>
<p align="left"><b>Door latches</b> - These latches are 1/4 turn latches
designed to hold the door tightly closed.</p>
<p align="left"><b>Reset button</b> - This button is provided for the user
to be able to reset the overload protection device on the starter without
opening the door. On a NEMA 3 enclosure, this button is protected by
a heavy rubber cover.</p>
<p align="left"><b>Disconnect Switch</b> - This switch is provided to
control the internal mechanism that can disconnect the power source form
the starter to provide a safe condition when working on the starter.
This switch has a protective latch mechanism that prevents the door from
being opened when the power is on and it also prevents the power from
being turned on when the door is open.</p>
<p align="left"><b>Fused Disconnect</b> - Disconnect switch that is
attached to a fuse block, providing fused protection to the motor.</p>
<p align="left"><b>Non-Fused Disconnect</b> - Disconnect switch only.
(many Non-Fused Disconnect starters still have provisions to add fuse
clips later)</p>
<p align="left"><b>Breaker Disconnect</b> - Disconnect switch that is
attached to a circuit breaker as opposed to a fuse block.</p>
<p align="left"><b>Cabinet lock</b> - Swing latch drops to help secure the
door. A hole is provided on the latch for a pad lock or other
lock-out device.</p>
<p align="left"><b>Extra control or pilot light holes</b> - Each starter
comes with ample holes for pilot light and control devices. When not
used, they are secured with a weatherproof plug.</p>
<p align="left"><b>Pilot Lights</b> - Lights that are triggered by various
functions of the starter indicating the current condition of the starter,
power, motor or other device.</p>
<p align="left"><b>Hand-Off-Auto switch</b> - Commonly referred to as an <b>HOA</b>
switch. This control switch is for a device that may need to be
turned on manually (hand) and also can be turned on via a remote (Energy
management system, thermostat, flow switch) device or system. This
is the typical location for the primary control switching operator.
Others are possibilities are Start-Stop, Emergency Stop, High-Low. </p>
