Introduction
UL
Disconnect Switches
UL 98—Enclosed and
Deadfront Switches
(CSA C22.2 No. 4)
These requirements cover
enclosed or deadfront
switches, with or without
provision for fuses, at 600V
or less. These products are
used as disconnecting means
without restrictions; they are
heavy-duty products requiring
2.00 inches (50.0 mm)
minimum of creepage
distance between phases,
which gives maximum safety
for users and installation.
The short-circuit withstand
of those products goes up
to 200 kA.
UL 489—Molded Case
Switches (CSA C22.22 No. 5)
These requirements cover
molded case circuit breakers,
molded case switches and
fused molded case switches,
rated at 600V or less and
6000A or less.

UL Standards for Electrical
Machinery
UL 508—Industrial Control
Equipment (CSA C22.2 No. 14)
These requirements cover
manual, magnetic and solid-
state starters and controllers,
overload relays, pushbuttons,
selector switches and
control lights.
These products are smaller,
requiring only a creepage
distance between phases
of 0.50 inch (12.7 mm).
Their use as a disconnecting
means is limited to local
disconnection of motors.
These products can be used
as a disconnect means only
when they have been
additionally tested “suitable
as motor disconnect.” This
additional testing ensures
that the switch has a proper
closing capacity on a short
circuit. UL 508 devices
cannot be used as main
disconnect of an electrical
panel, e.g., at the entrance
of control panels.
A manual motor controller
marked “suitable as motor
disconnect” shall be installed
only on the load side of
the branch circuit protective
device [UL 508A 30.33
and NEC 430.109 (6)].
