Disconnect Switches
UL®/CSA® Standards for
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 inches (50mm) minimum
of creepage distance between phases,
which gives maximum safety for users and
installation. The short-circuit withstand of these
products goes up to 200kA.
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.
NFPA® 79 Electrical Standard for
Industrial Machinery
The following types of machines are identified
as industrial machinery:
UL® Standards for
Electrical Machinery
UL 508 – Industrial Control
Equipment (CSA C22.2 No. 14)
These requirements cover manual, magnetic
and solidstate 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 30.3.3 and NEC 430.109 (6)].

• Assembly machines
• Material handling machines,
including industrial robots and
transfer machines
• Inspection and testing machines, including

Meeting the requirements of UL508A and NFPA79
The disconnect shall be operable independent of the door position.
The disconnect must be operable, by qualified persons, independent of the door position without the use of accessory tools or devices.
Note: NFPA 79; Paragraph 5.3.3.1 (5).
An operating mechanism for the disconnecting means shall be operable independent of the
door position without the use of accessory tools or devices.
Note: UL 508A; Paragraph 66.6.3 c.
